MIC79110数据手册集成电路（IC）的电池充电器规格书PDF

描述 Description

The Micrel MIC79110 is a simple and accurate lithium ion battery charger. Featuring a built-in pass transistor, precision programmable current limiting (±5%), and precision voltage termination (±0.75% over temperature) all in a very small package, the MIC79110 packs full functionality into a small space.Other features of the MIC79110 include two independent end-of-charge indications, including a digital indication that is programmable with a resistor-to-ground and an analog current output that is proportional to the output current, allowing for monitoring of the actual charging current. Additional features include very low dropout (550mV over the temperature range), thermal shutdown, and reverse polarity protection. In the event the input voltage to the charger is disconnected, the MIC79110 also provides minimal reverse-current and reversed-battery protection.Available in both fixed 4.2V and adjustable outputs, the MIC79110 is offered in the leadless 10-pin 3mm x 3mm MLF® with an operating junction temperature range of -40°C to +125°C.

特性 Features

• Input voltage range: 2.5V to 16V
• High output voltage accuracy of ±0.75% over -5°C to +60°C
• Current Limit ±5% accurate from -5°C
