| XC61A Series Low Voltage Detectors (0.8V~2.0V) HP010199 x CMOS x Mini Mold Package x Highly Accurate 2% (1%) x Low Power Consumption 1.0A Typ. (VIN=2V ) s Applications q Microprocessor reset circuits q Memory battery back-up circuits q Power-on reset circuits q Power failure detection q System battery life and charge voltage monitors s General Description The XC61A is a highly precise detector series manufactured using CMOS and laser trimming technologies. The series is very accurate and offers standard voltage sourced low power consumption.The series consists of hysteresis, output driver, and linear characterised delay circuits, together with a comparator. Detect voltage is extremely accurate with minimal temperature drift. Both CMOS and Nchannel open drain output configurations are available. Integrating the above functions in a single, mini-molded package, the XC61A series offers significant space saving and high-density mounting, suitable for use with portable products. s Features Highly accurate: Detect voltage 2% (1% for semi-custom products) Low power consumption: Typ.1.0A (VIN=2V) Selectable detect voltage: 0.8V ~ 2.0V in 0.1V increments. Operating voltage: From 0.7V ~ 6.0V.

The products that have 1% Detect Voltage (VDF) accuracy are semi-custom products. 2. An additional resistor connected between the VIN pin and the supply voltage may cause alterations in the characteristics due to the increasing values of VDR. s Notes on Use Where a resistor (RIN) is connected between VIN and the power supply, use the N-ch open drain configuration. In order to prevent oscillation please ensure that RIN = 1k or less and that C = 0.1F or more. s Functional Description The following designators q-y refer to the timing diagram below: qWhen the Input Voltage (VIN) is higher than the Detect Voltage (VDF) level, output at the VOUT pin is equal to VIN. (High impedance exists with the N-channel open drain output configuration). wWhen the Input Voltage (VIN) falls below the Detect Voltage (VDF) level, the Output Voltage (VOUT) is equal to the Ground Voltage (VSS) level. eWhen the Input Voltage (VIN) falls below the Minimum Operating Voltage (VMIN) level, output becomes unstable. In this condition, if there is an output pull-up, VIN will be the output. rWhen the Input Voltage (VIN) rises above the ground voltage (Vss) level, output becomes unstable between the Ground Voltage (VSS) level and the Minimum Operating Voltage (VMIN) level. Between the VMIN and VDR levels the Ground Voltage (Vss) level is maintained. tWhen the Input Voltage (VIN) rises above the Detect Release Voltage (VDR) level, output at the VOUT pin is equal to VIN. (High impedance exists with the N-channel open drain output configuration). yThe difference between VDR and VDF represents the hysteresis range.
