ASM1816 - Voltage Supervisors Device

General Description

The ASM1816 is a voltage supervisory device with low power, 3.3 V/3 V mP Reset, active LOW, open

drain output.

Maximum supply current over temperature is a low 15 mA (at 3.6 V).

The ASM1816 generates an active LOW reset signal whenever the monitored supply is out of tolerance.

ASM1816 Low Power, 3.3 V/3.0 V, mP Reset, Active LOW, Open-Drain Output Description The ASM1816 is a voltage supervisory device with low−power, 3.3 V/3 V mP Reset, active LOW, open−drain output. Maximum supply current over temperature is a low 15 mA (at 3.6 V). The ASM1816 generates an active LOW reset signal whenever the monitored supply is out of tolerance. A precision reference and comparator circuit monitor power supply (VCC) level. Tolerance level options are 5%, 10%, 15% and 20%. When an out−of−tolerance condition is detected, an internal power−fail signal is generated which forces an active LOW reset signal. After VCC returns to an in−tolerance condition, the reset signal remains active for 150 ms to allow the power supply and system microprocessor to stabilize.
