MST4056KP Description

Short technical summary and product information.

The MST4056KP from Milestone Semiconductor Inc. is a versatile linear Li-Ion battery charger IC designed for various portable electronic devices. It provides a standard three-stage charging process: trickle, constant current, and constant voltage, supporting a continuous charge current of up to 1A.

This charger IC boasts high input voltage tolerance, withstanding transient surges up to 8V and operating continuously at 7V, making it suitable for complex or uncertain input conditions. It incorporates thermal regulation to maintain safe operating temperatures by adjusting output current based on chip temperature. The charge current limit is adjustable via an external resistor.

Key features include integrated MOSFETs, automatic recharge functionality, and dual indicator outputs for charging status, completion, no battery, and error states. It also includes input undervoltage protection and power path reverse current blocking. The MST4056KP is available in SOP-8L, SOP-8L-EP, and DFN 2x2-6 package types.

Applications for the MST4056KP include mobile phones, PDAs, MP3 players, portable chargers, power banks, electric toys, and other portable electronic devices.
