IC for CMOS System Reset
Monolithic IC PST35XX, 36XX Series
Outline
March 21, 2004
This system reset IC, developed using the CMOS process, has a built-in delay function. Ultra-low
consumption current of 1.0µA (typ.). has been achieved through use of the CMOS process. Also, detection
voltage is high-precision detection of ±2%. The small package MLF-4 (1.1 1.4 0.6mm) is used for space
saving.
Features
1. Ultra-low current consumption
1.0µA typ. (V
