Package | Pins | Size
Features
- Extremely-Low Quiescent Current: 0.62 µA at
VIN = 2.6 V - High Accuracy Threshold Voltage (±2.5%)
- Open-Drain Output
- Programmable Output Delay by External Capacitor
(130 ms Typical With 0.1 µF) - Input Voltage Range: 1 V to 6 V
- Pin-for-Pin Compatible With MC33465
Description
The LM8365 device is a micropower undervoltage sensing circuit that is ideal for use in battery-powered microprocessor based systems, where extended battery life is a key requirement.
Threshold voltages of 2.7 V and 4.5 V are available with an active-low, open-drain output. These devices feature a very-low quiescent current of 0.65 µA typical. The LM8365 features a highly accurate voltage reference, a comparator with precise thresholds and built-in hysteresis to prevent erratic reset operation, a time delayed output which can be programmed by the system designer, and specified Reset operation down to 1 V with extremely-low standby current.
Same functionality and pinout but is not an equivalent to the compared device:
