MB3841-Power Management Switch IC
Description The Fujitsu MB3841 is a channel power management IC with very low resistance switching. The MB3841 is designed for a variety of switching applications, featuring low input voltage operation (VIN >2.2 V) and resistance independent of the input voltage to remain stable. The switch current limit can be set externally over a wide range of 100 mA to 2 A: A safety function detects overcurrent conditions, sets immediate shutdown mode to an external switch and sends a notification signal. Therefore, the MB3841 is ideal for power management switch applications with USB specifications. In addition, the MB3841 has features that ensure precise shutdown, prevent reverse current switching in OFF mode, and a fast-discharging capacitor connected to the output.
