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 built–in 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 3–pin TO–226AA, 8–pin
SO–8 and Micro–8 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 (MC34164–3) or 5.0 V (MC34164–5) Power Supplies
Precise Comparator Thresholds Guaranteed Over Temperature
Comparator Hysteresis Prevents Erratic Reset
Reset Output Capable of Sinking in Excess of 6.0 mA
Internal Clamp Diode for Discharging Delay Capacitor
Guaranteed Reset Operation With 1.0 V Input
Extremely Low Standby Current: As Low as 9.0 µA
Economical TO–226AA, SO–8 and Micro–8 Surface Mount Packages
