MC34164, MC33164, NCV33164 Micropower Undervoltage Sensing Circuits The MC34164 series are undervoltage sensing circuits specifically designed for use as reset controllers in portable microprocessor based www.onsemi.com 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. The MC 1 1 devices are packaged in 3pin TO92 (TO226AA), micro size 2 2 3 3 TSOP5, 8pin SOIC8 and Micro8 surface mount packages. The STRAIGHT LEAD BENT LEAD NCV device is packaged in SOIC8. BULK PACK TAPE & REEL AMMO PACK Applications include direct monitoring of the 3.0 V or 5.0 V MPU/logic power supply used in appliance, automotive, consumer, TO92 (TO226AA) P SUFFIX and industrial equipment.
