General Description
MB39A132, which is used f or charging Li-ion batter y, is a synchronous rectification DC/DC con verter IC adopting pulse width modification (PWM).
It can control charge voltage and charge current separately and supports the N-ch MOS driver.
In addition, MB39A132 is suitable for down-conversion.
Key Features
- S.
- Supports 2/3/4-Cell battery pack Two built-in constant current control loops Built-in AC adapter detection function (ACOK pin) Charge voltage setting accuracy: 0.5 (Ta 25 C to 85 C) Charge voltage control setting can be selected without using an y external resistor. (4.00 V/Cell, 4.20 V/ Cell, 4.35 V/Cell) Output voltage can also be freely set by using the external resistor. Two built-in high-precision current detection amplifiers :In.
