Description
The SMB1357 is a programmable single-cell lithium-ion/lithium-polymer battery charger designed for various portable applications. It offers a simple and efficient way to charge high-capacity Li-Ion batteries through a USB port or AC adapter. Unlike conventional chargers, the SMB1357 operates with high efficiency, eliminating internal temperature rise and localized hot spots in handheld devices. It features Summit's proprietary TurboChargeTM mode, which allows a 750mA charge current from a 500mA USB port, resulting in significantly reduced charge times. The charger has multiple programmable charge control settings, including qualification, trickle-charge, pre-charge, constant current/constant voltage, and termination/safety settings. These settings can be adjusted using a serial I2C/SMBus interface, making the SMB1357 a flexible solution. The charger also offers a wide range of protective features, such as over-current, under/over-voltage, and thermal protection. With ultra-precise ADOC™ technology, the SMB1357 enables accurate control of battery float voltage and improves battery capacity utilization. The charger is available in a compact 1.3mm x 2.1mm uCSP™ package or a 5x5 QFN-32 package and is suitable for use in temperatures ranging from -30°C to +85°C.
