概要

Description

MAX1651CSA is a Maxim Integrated Li‑ion battery‑charger controller. It provides a complete charge-management solution for a single‑cell Li‑ion/Li‑poly pack, controlling charge current and termination while protecting the battery and system. It typically drives an external pass element and implements a CC/CV charging profile with optional preconditioning and end‑of‑charge detection.
Key features:
- CC/CV charging with preconditioning for deeply discharged cells
- End‑of‑charge termination by a current threshold
- Battery temperature monitoring and safety protections
- Overcurrent/overvoltage/short‑circuit protection and fault signaling
- Designed to work with an external MOSFET/pass element; includes status/control connections
- CSA suffix denotes a specific package/version variant
Note: For exact electrical specs, pinout, and package details, consult the MAX1651CSA datasheet.

Features

Here are the typical features of MAX1651CSA (battery charger/power-path controller):
- Integrated switching battery charger with power-path management for portable devices
- Constant-current/constant-voltage charging algorithm with automatic termination
- Preconditioning/trickle charging for deeply discharged cells
- Programmable charge current (via external resistor) and end-of-charge timing
- Battery temperature monitoring via external thermistor input
- Auto-recharge when battery voltage falls below threshold
- Power-path load sharing to power the system while charging
- Robust safety protections: over/undervoltage, overcurrent/short-circuit, and overtemperature
- Fault/status indicators and enable/disable control options
- Wide input voltage range and high efficiency operation
- Suitable for compact/low-profile packaging (CSA variant)
Note: For exact electrical specs, pinout, and programming details, please consult the MAX1651CSA datasheet.

Package

MAX1651CSA comes in an 8-pin SOIC (8-lead small-outline) package.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC/MSOP with CSA suffix).
- Function: Li‑ion battery charger controller for a single-cell pack. It provides constant-current/constant-voltage charging using an external pass element, senses battery voltage and current, supports programmable charge current (via a PROG input), includes optional temperature sensing, and offers status signals (charging/charge-complete).

Manufacturer

MAX1651CSA is manufactured by Maxim Integrated Products, Inc. Maxim Integrated is a semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, including power-management and interface ICs. It is now a wholly owned subsidiary of Analog Devices.

Application

Applications of MAX1651CSA:
- Li-ion/Li-polymer battery charging and management for portable devices
- Power-path/battery-backup controllers for telecom, networking, and data‑center equipment
- Automotive 12V battery management and protection schemes
- AC/DC adapters, offline chargers, and small power supplies
- Hot-swap controllers and DC‑DC converter front ends in consumer/industrial equipment
