SGMICRO SGM41007YTN6G/TR

The SGM41007 series is designed for heating control and battery overcharge, over-discharge, short-circuit, and over-temperature protection. Its internal circuitry includes a heating control module with timeout protection, a battery protection module, and a button-reading and indication module. Heating control modes include maximum power output without power level control, and high/low three-level power output with automatic battery voltage compensation. The battery protection prevents excessive discharge and overcharge, works with an external PTC for over-temperature detection, and uses internal temperature sensing to prevent sustained short-circuit damage to the IC itself and the battery. The IC is designed for single-button operation to select operating parameters, capable of recognizing single/multiple button presses, long-press duration, and their combinations to trigger ignition, display power level, display battery level, select charge power, and power on/off. The display includes timed continuous illumination, slow blinking, and strobe states for intuitive indication of current status and parameter configuration.

The SGM41007 series is available in a TSOT-23-6 green package, with an operating temperature range of -40°C to +85°C and an internal protection temperature of +165°C.
