This document introduces the features and characteristics of the ASM1233D-L/D/M series products, including low power consumption, 5V/3.3V µP Reset, active low, open drain output, etc.
The ASM1233D-L, ASM1233D, and ASM1233M are voltage supervisors designed with low-power consumption and an active LOW, open-drain output. These devices generate a reset signal whenever the monitored supply voltage is out of tolerance, ensuring system stability during power-up and power-down events.
| Supply Voltage | 1.2V to 5.5V |
|---|---|
| Operating Temperature Range | -40°C to +85°C |
| Maximum Supply Current (3.3V) | 15µA |
| Maximum Supply Current (5V) | 20µA |
| Reset Delay | 350ms |
| Output Type | Open-Drain |
| Internal Pull-up Resistor | 5kΩ |
| Packages | SOT-223, SO-8, TO-92 |
The reset signal remains active for 350ms after the power supply voltage returns to an in-tolerance condition.
The maximum supply current over temperature is 15µA for 3.3V devices.
The devices are available in SOT-223, SO-8, and TO-92 packages.
