AF4064 Standalone Linear Li-Ion Battery Charger

PIN No. SOT23-5 1 2 NAME CHRG GND 3 BAT 4 VCC 5 PROG - - NC (1) I = Input; O = Output; P = Power AF-V1.0 TYPE(1) DESCRIPTION AND REQUIRED COMPONENTS Open Drain Charge Status Output. When the battery is being charged, the CHRG pin is pulled low O by an internal N-channel MOSFET switc.

Standalone Linear Li-Ion Battery Charger with Thermal Regulation AF4064 INTRODUCTION: The AF4064 is a complete constant-current/ constant voltage linear charger for single cell lithium-ion batteries. Its SOT package and low external component count make the AF4064 ideally suited for space limited portable applications. Furthermore, the AF4064 is specifically designed to work within USB power specifications. No external sense resistor is needed, and no blocking diode is required .
