CMOS Voltage Detector
Description
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)
