Voltage Detector IC Series
Standard CMOS
Voltage Detector IC
BD48Exxx-M series BD49Exxx-M series (for Automotive Accessories)
●General
Description
ROHM’s BD48Exxx-M and BD49Exxx-M series are
highly accurate, low current consumption Voltage
Detector IC series. The line up 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.
●Key
Specifications
Detection voltage:
2.3V to 6.0V (Typ.),
0.1V steps
High accuracy detection voltage:
±1.0%
Ultra-low current consumption:
0.9µA (Typ.)
Operating temperature range:
