BD4844G-TR Datasheet, PDF (1/18 Pages) Rohm – Standard CMOS Voltage Detector IC

Voltage Detector IC Series
Standard CMOS
Voltage Detector IC
BD48xxx series BD49xxx series
●General Description
ROHM’s BD48xxx and BD49xxx series are highly
accurate, low-current Voltage Detector IC series. The
family includes BD48xxx devices with N-channel open
drain output and BD49xxx devices with CMOS output.
The devices are available for specific detection voltages
ranging from 2.3V to 6.0V in increments of 0.1V.
●Features
High accuracy detection
Ultra-low current consumption
Two output types (Nch open drain and CMOS output)
Wide Operating temperature range
Very small and low height package
Package SSOP5 is similar to SOT-23-5 (JEDEC)
Package SSOP3 is similar to SOT-23-3 (JEDEC)
