CE3150B Datasheet (Chipower) - Standalone Linear Li-Ion Battery Charger

CE3150B, Standalone Linear Li-Ion Battery Charger

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 switch.

When the CE3150B detects an undervoltage lockout condition, CHRG pin is forced high impedance.

Standalone Linear Li-Ion Battery Charger with Thermal Regulation CE3150B Series INTRODUCTION: The CE3150B 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 CE3150B ideally suited for space limited portable applications.

Furthermore, the CE3150B is specifically designed to work within USB power specifications.

No external sense resistor is needed, and no blocking dio
