APPLICATIONS
(Rechargeable Battery) Synchronous Rectification DC/DC Converter IC for Charging Li-ion Battery MB39A132●
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. MB39A132 suppor ts a wide input v oltage range, enables low current consumption in standb y mode, and can control the charge voltage and charge current with high precision, which is perfect for the built-in Li-ion battery charger used in devices such as notebook PC.●
FEATURES
●●
●
●
● 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.
