The ASM161 and ASM162 are cost effective, low power supervisory circuits that monitor power supplies in microprocessor, microcontroller and digital systems. They have an improved manual reset architecture, low power consumption, and are ideal for use in portable and battery operated equipment.
The ASM161 and ASM162 are cost-effective, low-power microprocessor supervisory circuits designed to monitor power supplies in digital systems. These devices assert a reset when the supply voltage drops below a specific threshold and remain asserted for at least 800ms after the voltage recovers.
| Supply Current (Typical) | 6uA at 5.5V |
|---|---|
| Reset Pulse Width Minimum | 800ms |
| Package Type | SOT-143 |
The reset pulse period generated by a manual reset transition has a minimum duration of 800ms.
Yes, the ASM161 has an open-drain, active-LOW RESET output that requires an external pull-up resistor.
