mc34160 MC33160 http://onsemi.com 6 operating description the mc34160 series is a monolithic voltage regulator and supervisory circuit containing many of the necessary monitoring functions required in microprocessor based systems. it is specifically designed for appliance and industrial applications, offering the designer a cost effective solution with minimal external components. these devices are specified for operation over an input voltage of 7.0 v to 40 v, and with a junction temperature of 40 to +150 c. a typical microprocessor application is shown in figure 10. regulator the 5.0 v regulator is designed to source in excess of 100 ma output current and is short circuit protected. the output has a guaranteed tolerance of 5.0% over line, load, and temperature. internal thermal shutdown circuitry is included to limit the maximum junction temperature to a safe level. when activated, typically at 170 c, the regulator output turns off. in specific situations a combination of input and output bypass capacitors may be required for regulator stability. if the regulator is located an appreciable distance ( 4 ) from the supply filter, an input bypass capacitor (c in ) of 0.33 m f or greater is suggested. output capacitance values of less than 5.0 nf may cause regulator instability at light load ( 1.0 ma) and cold temperature. an output bypass capacitor of 0.1 m f or greater is recommended to ensure stability under all load conditions. the capacitors selected must provide good high frequency characteristics. good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator does not have external sense inputs. reference the 2.6 v bandgap reference is short circuit protected and has a guaranteed output tolerance of 5.0% over line, load, and temperature. it is intended to be used in conjunction with the power warning and uncommitted comparator. the reference can source in excess of 2.0 ma and sink a maximum of 10 m a. for additional current sinking capability, an external load resistor to ground must be used. reference biasing is internally derived from either v cc or v o , allowing proper operation if either drops below nominal. chip disable this input is used to switch the ic into a standby mode. when activated, internal biasing for the entire die is removed causing all outputs to turn off. this reduces the power supply current (i cc ) to less than 0.3 ma. comparators three separate comparators are incorporated for voltage monitoring. their outputs can provide diagnostic information to the microprocessor, preventing system malfunctions. the reset comparator inverting input is internally connected to the 2.6 v reference while the noninverting input monitors v o . the reset output is active low when v o falls approximately 180 mv below its regulated voltage. to prevent erratic operation when crossing the comparator threshold, 70 mv of hysteresis is provided. the power warning comparator is typically used to detect an impending loss of system power. the inverting input is internally connected to the reference, fixing the threshold at 2.6 v. the input power source v in is monitored by the noninverting input through the r 1 /r 2 divider (figure 10). this input features an adjustable 10 m a to 50 m a current sink i h that is programmed by the value selected for resistor r h . a default current of 6.5 m a is provided if r h is omitted. when the comparator input falls below 2.6 v, the current sink is activated. this produces hysteresis if v in is monitored through a series resistor (r 1 ). the comparator thresholds are defined as follows: r1 r 2 1 + i ib r 1 v th(lower) = v ref r1 r 2 1 + + i h r 1 v th(upper) = v ref the nominal hysteresis current i h equals 1.2 v/r h (figure 4). the uncommitted comparator can be used to synchronize the microprocessor with the ac line signal for timing functions, or for synchronous load switching. it can also be connected as a line loss detector as shown in figure 11. the comparator contains 200 mv of hysteresis preventing erratic output behavior when crossing the input threshold. the power warning and uncommitted comparators each have a transistor baseemitter connected across their inputs. the base input normally connects to a voltage reference while the emitter input connects to the voltage to be monitored. the transistor limits the negative excursion on the emitter input to 0.7 v below the base input by supply current from v cc . this clamp current will prevent forward biasing the ic substrate. zener diodes are connected to the comparator inputs to enhance the ics electrostatic discharge capability. resistors r 1 and r in must limit the input current to a maximum of 2.0 ma. each comparator output consists of an open collector npn transistor capable of sinking 2.0 ma with a saturation voltage less than 0.4 v, and standing off 40 v with minimal leakage. internal bias for the reset and power warning comparators is derived from either v cc or the regulator output to ensure functionality when either is below nominal.
