MC34064D-5R2 Undervoltage Sensing Circuit
DESCRIPTION: The MC34064 is an undervoltage sensing circuit specifically
designed for use as a reset controller in microprocessor-based
systems. It offers the designer an economical solution for low voltage
detection with a single external resistor. The MC34064 features a
trimmed-in-package bandgap reference, and a comparator with
precise thresholds and built-in hysteresis to prevent erratic reset
operation. The open collector reset output is capable of sinking in
excess of 10mA, and operation is guaranteed down to 1.0V input with
low standby current.
FEATURES:
- Trimmed-In-Package Temperature Compensated Reference
- Comparator Threshold of 4.6 V at 25 Degrees C
- Precise Comparator Thresholds Guaranteed Over Temperature
- Comparator Hysteresis Prevents Erratic Reset
- Reset Output Capable of Sinking in Excess of 10mA
- Internal Clamp Diode for Discharging Delay Capacitor
- Guaranteed Reset Operation with 1.0V Input
- Low Standby Current
- Package: SOIC-8
- Operating Temperature Range: 0 Degrees C to +70 Degrees C
These parts are new and unused -- very nice. [Note: This part currently sells for $0.93 for one at Digi-Key.]
