CE3151 Datasheet (Chipower) - Standalone Linear Li-Ion Battery Charger

CE3151, Standalone Linear Li-Ion Battery Charger

TYPE(1) DESCRIPTION AND REQUIRED COMPONENTS Open Drain Charge Status Output.

When the battery is being charged, the O CHRG pin is pulled low by an internal N-channel MOSFET switch.

When the CE3151 detects an undervoltage lockout condition, CHRG pin is forced high impedance.

I Ground Terminal

Standalone Linear Li-Ion Battery Charger with Thermal Regulation CE3151 Series INTRODUCTION: The CE3151 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 CE3151 ideally suited for space limited portable applications.

Furthermore, the CE3151 is specifically designed to work within USB power specifications.

No external sense resistor is needed, and no blocking diode is
