3.4
Direct output drive of an external P-channel MOSFET
pass transistor for current and voltage regulation.
3.5
A supply voltage of 4.5V to 5.5V is recommended.
Bypass to GND with a minimum of 10 µF.
3.6
Charge current is sensed via the voltage developed
across an external precision sense resistor. The sense
resistor must be placed between the supply voltage
