●General
Description
ROHM standard CMOS reset IC series is a high-accuracy,
low current consumption reset IC series. The lineup was
established with two output types (Nch open drain and
CMOS output) and detection voltage range from 0.9V to
4.8V in increments of 0.1V, so that the series may be
selected according to the application at hand.
●Features
Ultra-low current consumption
High accuracy detection, Ultra-low voltage detection
Two output types (Nch open drain and CMOS output)
Wide operating temperature range
Very small and low height package
Package SSOP5 and SOP4 is similar to SOT-23-5 and
SC-82 respectively (JEDEC)
