Power Management Switch IC

MB3841

■ DESCRIPTION

The FUJITSU MB3841 is a one-channel power management switch IC with extremely low on resistance.

The MB3841 is designed for a variety of switching applications, featuring operation from low input voltages

(V^IN> 2.2 V) and stable on resistance that does not depend on input voltage. The switch current limit can be

externally set over a wide range from 100 mA to 2 A. A safety function detects overcurrent conditions, immediately

sets the switch to off mode and sends an external notification signal. The MB3841 is therefore ideal for power

management switching applications with USB specifications.

In addition, the MB3841 has features that ensure accurate on-off switching by preventing reverse current in off

mode, as well as rapid discharge of capacitors connected to output.

■ FEATURES

• Low on resistance switch (typ. 45 mΩ)

• Low input voltage operation (2.2 V to 5.5 V)

• Switch current (max. 2 A)

• UVLO (V^TH= 1.9 V)

• External settings for soft start time and switch current limit

• On-chip overheating and overcurrent detection (output off latching)

• On-chip abnormal state detection circuit (O.C. pin)

• On-chip output pin discharge control circuit

• Supply current = 0 µA in standby mode (CONTROL < 0.8 V)

• Reverse current protection function in off mode
