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
