MIC79050

Simple Lithium-Ion Battery Charger

Features

General Description

• High-Accuracy Charge Voltage: ±0.75% over

–5°C to + 60°C (Li-ion charging temperature

range)

The MIC79050 is a simple single-cell lithium-ion battery

charger. It includes an on-chip pass transistor for high

precision charging. Featuring ultra-high precision

(±0.75% over the Li-ion battery charging temperature

range) and “zero” off-mode current, the MIC79050

provides a very simple, cost effective solution for

charging lithium-ion battery.

• Zero Off-Mode Current

• 10 µA Reverse Leakage

• Ultra-Low 380 mV Dropout at 500 mA

• Wide Input Voltage Range

Other features of the MIC79050 include current-limit

and thermal shutdown protection. In the event the input

voltage to the charger is disconnected, the MIC79050

• Logic-Controlled Enable Input (8-Lead Devices

Only)

• Thermal Shutdown and Current-Limit Protection

reversed-battery protection.

The MIC79050 is a fixed 4.2V device and comes in the

thermally-enhanced MSOP-8, SOIC-8, and SOT-223

packages. The 8-lead versions also come equipped

with enable and feedback inputs. All versions are

specified over the temperature range of –40°C to

+125°C.
