ASM1815 is a low-power, 3.3V/3.0V µP Reset, active LOW, Push-Pull output voltage supervisory device.
The ASM1815 is a voltage supervisory device designed to generate an active LOW reset signal when the monitored power supply is out of tolerance. It features a precision temperature-compensated voltage reference and comparator, eliminating the need for external components. The device is available in TO-92 and SOT-23 packages and operates over an industrial temperature range of -40°C to +85°C.
| Supply Voltage | 1.2V to 5.5V |
|---|---|
| Operating Temperature Range | -40°C to +85°C |
| Reset Delay | 150ms |
| Output Stage | Push-Pull |
| Output Polarity | Active LOW |
| Output Capacitance | 10 pF |
| Operating Current (3.6V) | 15 µA max |
The reset signal remains active for 150ms after the power supply voltage returns to an in-tolerance condition.
The device is available in TO-92 and compact surface mount SOT-23 packages.
The maximum supply current is 15 µA at 3.6V and 20 µA at 5.5V.
