MB3802 Overview
The MB3802 is a power management switch incorporating two switch circuits with extremely low ON resistance. NO diode is required because the switch block is configured with an N-ch MOS to prevent reverse current at switch OFF. The MB3802 starts at a very low voltage (typical VIN > 2.2V) and a stable ON resistance is obtained irrespective of the switching voltage because the internal DC/DC converter applies the...
MB3802 Key Features
- Extremely low ON resistance: RON = 0.12 Ω (typical) RON = 0.06 Ω (typical at parallel connection)
- Reverse current protection at load side at switch OFF
- Operation start at low input voltage: VIN > 2.2 V (typical)
- Low power consumption At switch OFF: IIN (input voltage) = 0 µA, VIN = 0 V At switch ON: IIN = 230 µA, VIN = 5 V
- Load discharge function
- External control of ON/OFF time
- Break-before-make operation
