The ASM1233A is a low-power, 3.3V µP Reset, with an active LOW, open-drain output. Maximum supply current over temperature is a low 15µA.
The ASM1233A is a voltage supervisor designed to generate an active LOW reset signal when the monitored supply voltage is out of tolerance. It features a precision temperature-compensated reference and a 350ms reset delay to allow the microprocessor and power supply to stabilize after a power failure or voltage excursion. The device operates with a maximum supply current of 15µA and is available in a compact SOT-223 package.
| Supply Voltage | 1.2V to 5.5V |
|---|---|
| Operating Current | 15µA maximum |
| Reset Delay | 350ms |
| Operating Temperature Range | -40°C to +85°C |
| Package Type | SOT-223 |
| Output Stage | Open-Drain |
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.
The tolerance is 15% for the 3.3V ASM1233A.
