BD45451G-TR Electronic IC Chips Counter Timer Built-in CMOS Voltage Detector IC

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% „
