The ASM1810 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 voltage reference and comparator, eliminating the need for external components. The device operates over an extended industrial temperature range of -40°C to +85°C and is available in TO-92 and SOT-23 packages.
| Supply Voltage | 1.2V to 5.5V |
|---|---|
| Operating Temperature Range | -40°C to +85°C |
