IMP1 233D POWER MANAGEMENT Low Power, 5V µP Reset Key Features N Improved Dallas DS1233D replacement — Over 60% lower maximum supply current N Low Supply Current — 20µA maximum (5.
5V) — 15µA maximum (3.
6V) N Automatically restarts a microprocessor after power failure N 350ms reset delay after VCC returns to an in-tolerance condition N Active LOW power-up reset, 5kΩ internal pull-up N Precision temperature-compensated voltage reference and comparator N Eliminates external components N Motorola 68xxx and HC16 compatible N Compact surface mount SOT-223 package N Operating temperature – 40°C to +85°C – Active LOW, Open-Drain Output – 350ms Reset Period The IMP1233D supply voltage monitor is an improved, low-power replacement for the Dallas Semiconductor DS1233D.
Maximum supply current over temperature is a low 20µA, representing over 60 percent lower power as compared to the DS1233D.
The IMP1233D issues 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- and 15-percent.
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 IMP1233D is designed with a open-drain output stage and operates over the extended industrial temperature range.
Devices are available in compact surface mount SOT-223 packages.
Other low power products in this family include the IMP1810/11/12/15/ 16/17 and IMP1233M.
