IC for CMOS System Reset
Monolithic IC PST38XXU Series
April 16, 2001
Outline
This open drain output system reset IC, developed using the CMOS process. Super low consumption current
of 1.0µA typ. (PST3810 ~ PST3819) has been achieved through use of the CMOS process. Also, detection
voltage is high precision detection of ±±2.
Features
(1) Super low consumption current
(±) High precision detection voltage
(3) Operating range
1.0µA typ. (when VDD = (
-VDET) + ±.0V) PST3810 ~ PST3819
±±2
0.7 ~ 10V
(4) Wide operating temperature range
(5) Detection voltage
-
30 ~ +85°C
0.9 ~ 6.0V (0.1V step)
Package
SC-8±ABA, SC-8±ABB
Applications
(1) Microcomputer, CPU, MPU reset circuits
(±) Logic circuit reset circuits
(3) Battery voltage check circuits
(4) Back-up circuit switching circuits
(5) Level detection circuits
