Voltage Detector IC Series
Counter Timer Built-in
CMOS Voltage Detector IC
BD45xxx series
BD46xxx series
●General Description
ROHM’s BD45xxx and BD46xxx series are highly
accurate, low current consumption Voltage Detector ICs.
Because the counter timer delay circuit is built into
these series, an external capacitor for the delay time
setting is unnecessary. The lineup was established with
low output types (Nch open drain and CMOS output)
and detection voltages range from 2.3V to 4.8V in
increments of 0.1V, so that the series may be selected
according the application at hand.
●Features
Counter Timer Built-in
No delay time setting external capacitor required
Ultra-low current consumption
Two output types (Nch open drain and CMOS output)
Package SSOP5 is similar to SOT-23-5 (JEDEC)
●Key Specifications
Detection voltage:
2.3V to 4.8V (Typ.)
0.1V steps
High accuracy detection voltage:
±1.0%
Ultra-low current consumption:
0.85µA (Typ.)
Operating temperature range:
-40°C to +105°C
Three internal, fixed delay time:
50ms
100ms
200ms
●Package
