Micropower Undervoltage
Sensing Circuits
The MC34164 series are undervoltage sensing circuits specifically
designed for use as reset controllers in portable microprocessor based
systems where extended battery life is required. These devices offer the
designer an economical solution for low voltage detection with a single
external resistor. The MC34164 series features a bandgap reference, a
comparator with precise thresholds and builtin hysteresis to prevent erratic
reset operation, an open collector reset output capable of sinking in excess
of 6.0 mA, and guaranteed operation down to 1.0 V input with extremely low
standby current. These devices are packaged in 3pin TO226AA, 8pin
SO8 and Micro8 surface mount packages.
Applications include direct monitoring of the 3.0 or 5.0 V MPU/logic power
supply used in appliance, automotive, consumer, and industrial equipment.
Temperature Compensated Reference
Monitors 3.0 V (MC341643) or 5.0 V (MC341645) Power Supplies

Comparator hysteresis can be increased with the addition of resistor RH. The hysteresis equation has been simplified and does not account for the change of input current
Iin as Vin crosses the comparator threshold (Figure 8). An increase of the lower threshold
Vth(lower) will be observed due to Iin which is typically 10
A at 4.3 V. The
equations are accurate to
10% with RH less than 1.0 k
and RL between 4.3 k
and 43 k
