1 General Description
The AS1910 - AS1915 microprocessor supervisory circuits were designed to generate a reset when one of the two monitored supply voltages falls below a factorytrimmed threshold, and to maintain the reset for a minimum timeout period when both supplies are above their reset thresholds. Guaranteed to be in the correct state for VCC higher than +1.0V, these devices are ideal for multiple-voltage systems with strict monitoring requirements. The AS1913/AS1914/AS1915 feature factory-trimmed thresholds to monitor a primary voltage between 1.8 and 3.6V, and a secondary voltage between 0.9 and 2.5V. For the AS1910/AS1911/AS1912, a secondary monitoring voltage can be user-adjusted via an external resistor divider down to 0.6V. The devices are available with the reset output types listed in Table 1. Table 1.

Active-Low Reset Output (AS1910, AS1912, AS1913, AS1915). The RESETN signal toggles from high to low when VCC, VCC2, or RESETIN input drops below the factory-trimmed RESETN reset threshold (see Table 4 on page 4), or MRN is pulled low, or the watchdog triggers a reset. This output signal remains low for the reset timeout period after all supervised voltages exceed their reset threshold, or MRN goes low to high, or the watchdog triggers a reset. Active-High Reset Output (AS1911, AS1914). The RESET signal toggles from low to high when VCC, VCC2, or RESETIN input drops below the factory-trimmed reset threshold (see Table 4 on page 4), or MRN is pulled low, or the watchdog triggers a reset. This output signal remains high for the reset timeout period (see tRP on page 5) after all supervised voltages exceed their reset threshold, or MRN goes low to high, or the watchdog triggers a reset. Ground Active-Low Manual Reset Input. Pulling this pin low asserts a reset. This pin is connected to the internal 50k pullup to VCC. This reset remains active as long as MRN is low and for the reset timeout period (see tRP on page 5) after MRN goes high. Note: If the manual reset feature is not used, this pin should be unconnected or connected to VCC. Watchdog Input. If WDI remains high or low for longer than the watchdog timeout period (see tWD on page 6), the internal watchdog timer period expires and a reset is triggered for the reset timeout period (see tRP on page 5). The internal watchdog timer clears whenever a reset is a asserted or when WDI senses a rising or falling edge. Note: To disable the watchdog feature, this pin must be unconnected or connected to a tristate buffer output.

8 Detailed Description
The AS1910 - AS1915 supervisory circuits were designed to generate a reset when one of the two monitored supply voltages falls below its factory-trimmed trip threshold (see VTH on page 4 and VTH2 on page 4), and to maintain the reset for a minimum timeout period (see tRP on page 5) after all supplies have stabilized. The integrated watchdog timer (see Watchdog Input on page 10) helps mitigate against bad programming code or clock signals, and/or poor peripheral response. An active-low manual reset input (see Manual Reset Input on page 10) allows for an externally activated system reset.
RESET/RESETN
Whenever one of the monitored voltages falls below its reset threshold, the RESET output (AS1910, AS1912, AS1913, AS1915) asserts low or the RESETN output (AS1911, AS1914) asserts high. Once all monitored voltages have stabilized, an internal timer keeps the reset asserted for the reset timeout period (tRP). After the tRP period, the RESET or RESETN output return to their original state (see Figure 10).

The AS1910/AS1911/AS1912 feature a user-adjustable supervisory voltage input (RESETIN). The threshold voltage for RESETIN is between 0.61 and 0.65V (0.63 typ).

To monitor a voltage higher than 0.63V, connect a resistor divider network to the circuit as shown in Figure 12. For the circuit shown in Figure 12, the threshold at VMONITOR is:
VMONITOR_TRIP = 0.63V [(R1 + R2)/R2] Note: Since RESETIN is powered by VCC, VRESETIN must not be larger than VCC. (EQ 1)

Watchdog Input
The integrated watchdog feature can be used to monitor processor activity via pin WDI, and can detect pulses as short as 50ns. The watchdog requires that the processor toggle the watchdog logic input at regular intervals, within a specified minimum timeout period (1.5s, typ). A reset is asserted for the reset timeout period. As long as reset is asserted, the timer remains cleared and is not incremented. When reset is deasserted, the watchdog timer starts counting (Figure 11).
Note: The watchdog timer can be cleared with a reset pulse or by toggling WDI. Figure 13. Watchdog Timing Relationship
VCC tRST
RESETN
tRP
tWD
tRP
WDI
The RESET signal is the inverse of the RESETN signal.
The watchdog is internally driven low during most (87.5%) of the watchdog timeout period (see tWD on page 6) and high for the rest of the watchdog timeout period. When pin WDI is left unconnected, this internal driver clears the watchdog timer every 1.4s. When WDI is tri-stated or is not connected, the maximum allowable leakage current is 10A and the maximum allowable load capacitance is 200pF.
Note: The watchdog function can be disabled by leaving pin WDI unconnected or connecting it to a tri-state output buffer.
Manual Reset Input
The active-low pin MRN is used to force a manual reset. This input can be driven by CMOS logic levels or with opendrain collector outputs. Pulling MRN low asserts a reset which will remain asserted as long as MRN is kept low, and for the timeout period (see tRP on page 5) after MRN goes high (140ms min). The manual reset circuitry has an internal 50k pullup resistor, thus it can be left open if not used. To create a manual-reset circuit, connect a normally open momentary switch from pin MRN to GND (see Figure 1 on page 1); external debounce circuitry is not required in this configuration. If MRN is driven via long cables or the device is used in a noisy environment, a 0.1F capacitor between pin MRN and GND will provide additional noise immunity.

9 Application Information
Watchdog Input Current
The watchdog input is driven through an internal buffer and an internal series resistor from the watchdog timer (see Figure 11 on page 9). When pin WDI is left unconnected (watchdog disabled), the watchdog timer is serviced within the watchdog timeout period (see tWD on page 6) by a low-high-low pulse from the counter chain. For minimum watchdog input current (minimum overall power consumption), pull WDI low for most of the watchdog timeout period, pulsing it low-high-low once within the first 7/8 (87.5%) of the watchdog timeout period to reset the watchdog timer.
Note: If WDI is externally driven high for the majority of the timeout period, up to 160A can flow into pin WDI.
Interfacing to Bi-Directional CPU Reset Pins
Since the reset outputs of the AS1912 and AS1915 are open drain, these devices interface easily with processors that have bi-directional reset pins. Connecting the processor reset output directly to the AS1912/AS1915 RESETN pin with a single pullup resistor (see Figure 14) allows the AS1912/AS1912 to assert a reset.

Fast Negative-Going Transients
Fast, negative-going VCC transients normally do not require the CPU to be shutdown. The AS1910 - AS1915 are virtually immune to such transients. Resets are issued to the CPU during power-up, powerdown, and brownout conditions.
Note: VCC transients that go 100mV below the reset threshold and last 55s typically will not assert a reset pulse.
Valid Reset to VCC = 0
The AS1910 - AS1915 are guaranteed to operate properly down to VCC = 1V. For applications requiring valid reset levels down to VCC = 0, a pulldown resistor to active-low outputs (push/pull only) and a pullup resistor to active-high outputs (push/pull only) will ensure that the reset line is valid during the interval where the reset output can no longer sink or source current.
Watchdog Tips
Careful consideration should be taken when implementing the AS1910 - AS1915 watchdog feature. One method of supervising software code execution is to set/reset the watchdog input at different places in the code, rather than pulsing the watchdog input high-low-high or low-high-low. This method avoids a loop condition in which the watchdog timer would continue to be reset inside the loop, preventing the watchdog from ever timing out. Figure 15 shows a flowchart where the input/output driving the watchdog is set high at the beginning of the routine, set low at the beginning of every subroutine, then set high again when the routine returns to the beginning. If the routine should hang in a subroutine, the problem would quickly be corrected, since the I/O is continually set low and the watchdog timer is allowed to time out, causing a reset or interrupt to be issued (see Watchdog Input Current on page 11). This method results in higher averaged WDI input current over time than a case where WDI is held low for the majority (87.5%) of the timeout period and periodically pulsing it low-high-low.
