●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)
