Voltage Detector (Reset) IC Series

Free Time Delay Setting

CMOS Voltage Detector (Reset) IC

BD52xxG-1 Series

General Description

Key Specifications

ROHM's Free Time Delay Setting CMOS Voltage

Detector ICs are highly accurate, with ultra-low current

consumption feature that uses CMOS process. Delay

time setting can be control by an external capacitor. The

lineup includes N-channel open drain output

(BD52xxG-1). The devices are available for specific

detection voltage ranging from 0.9 V to 5.0 V with 0.1 V

increment. The time delay has ±30 % accuracy in the

overall operating temperature range of -40 °C to 85 °C.

◼ Detection Voltage Accuracy:

±1.0 % ±5 mV (V_DET= 0.9 V to 1.6 V)

±0.9 % (V_DET= 1.7 V to 5.0 V)

◼ Detection Voltage:

0.9 V to 5.0 V (Typ)

0.1 V step

◼ Ultra-Low Current Consumption:

270 nA (Typ)

◼ Time Delay Accuracy:

±30 % (-40 °C to +85 °C,

CT pin capacitor ≥ 1 nF)
