Low Power, 3.3V, µP Reset, Active LOW, Open-Drain Output
November 2003
General Description
The ASM1233A is a voltage supervisor with low-power, 3.3V
µP Reset, with an active LOW, open-drain output. Maximum
supply current over temperature is a low 15µA.
The ASM1233A 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. The tolerance is 15% for the 3.3V, ASM1233A. 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 350ms to allow the power supply and system
microprocessor to stabilize.
The ASM1233A is designed with a open-drain output stage and
operates over the extended industrial temperature range.
Devices are available in compact SOT-223 packages.
Other low power products in this family include the ASM1810/
11/12/15/16/17, ASM1233D, and ASM1233M
