SYNCHRONOUS RECTIFICATION DC/DC CONVERTER IC FOR CHARGING LI-ION BATTERY INTEGRATED CIRCUITS CIRCUITO INTEGRADO IC SMT

DESCRIPTION
MB39A132, which is used for charging Li-ion battery, is a synchronous rectification DC/DC converter 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 has an AC adapter detection comparator, which is independent of the DC/DC converter control block, and can control the source supplying voltage to the system. MB39A132 supports a wide input voltage range, enables low current consumption in standby 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 (ACOK pin)
Charge voltage setting accuracy: 0.5% (Ta 25 C to 85 C)
Charge voltage control setting can be selected without using any 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 :Input offset voltage: 3 mV :Detection accuracy: 1 mV ( INC1, INC2 3 V to VCC)
Charge current control setting can be selected without using any external resistor. (RS 20 m: 2.85 A) Charge current can also be freely set by using the external resistor.
Switching frequency can be set by using the external resistor (MB39A132 has a built-in frequency setting capacitor.):100 kHz to 2 MHz
Built-in off time control In standby mode (Icc 6 A Typ), only the AC adapter detection is in operation.

APPLICATIONS
Internal charger used in notebook PC
Handy terminal device
