IC for CMOS System Reset
Monolithic IC PST35XX, 36XX Series
March 21, 2004
Outline
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 SSON-4A (1.1 1.4 0.6mm) is used for space
saving.
