The ADPL83200 controls an external P-channel MOSFET to create a near-ideal diode function for power switchover or load sharing. This permits highly efficient OR’ing of multiple power sources for extended battery life and low self-heating. When conducting, the voltage drop across the Metal-oxidesemiconductor field-effect transistor (MOSFET) is typically 20mV. For applications with a wall adapter or other auxiliary power source, the load is automatically disconnected from the battery when the auxiliary source is connected. Two or more ADPL83200s can be interconnected to allow load sharing between multiple batteries or charging multiple batteries from a single charger.
The wide supply operating range supports operation from one to six Li-Ion cells in series. The low quiescent current (11μA typical) is independent of the load current. The gate driver includes an internal voltage clamp for MOSFET protection.
The STAT pin can be used to enable an auxiliary P-channel MOSFET power switch when an auxiliary supply is detected. This pin may also be used to indicate to a microcontroller that an auxiliary supply is connected. The control (CTL) input enables the user to force the primary MOSFET off and the STAT pin low.
The ADPL83200 is available in a low-profile (1mm) ThinSOT package.
