S8254 datasheet

 

Description

The S8254 Series is a protection IC for 3-serial- or4-serial-cell lithium-ion / lithium polymer rechargeable batteries and includes a high-accuracy voltage detector and delay circuit.

The S-8254A Series protects both 3-serial or 4-serial cells using the SEL pin for switching.

 

Features

1. High-accuracy voltage detection for each cell

2. Three-level overcurrent protection

3. Switchable between a 3-serial cell and 4-serial cell using the SEL pin

4. Charge/discharge operation can be controlled via the control pins

 

Applications:

1. Lithium-ion rechargeable battery packs

Posted on by pinout

Part Number: LT3652

Function: Power Tracking 2A, Battery Charger

Package: DFN 12 Pin Type

Manufacturer: Linear Technology, Analog Devices

Pinouts:

LT3652 datasheet

 

Description

The LT3652 is a complete monolithic step-down battery charger that operates over a 4.95V to 32V input voltage range.

The device provides a constant-current/constant-voltage charge characteristic, with maximum charge current externally programmable up to 2A.

The charger employs a 3.3V float voltage feedback reference, so any desired battery float voltage up to 14.4V can be programmed with a resistor divider.
