Chip Fujitsu MB39A132 Synchronous Rectification DC/DC Converter, new

Synchronous Rectification DC/DC Converter IC for Charging Li-ion Battery

- 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 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 mΩ: 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 function
- In standby mode (Icc=6μA Typ), only the AC adapter detection function is in operation
