The SMB135 is a programmable single-cell lithium-ion/lithium-polymer battery charger for a variety of portable applications. The device provides a simple and efficient way to charge high-capacity Li-Ion batteries via a USB port or an AC adapter. Unlike conventional devices, the IC’s high-efficiency operation eliminates large internal temperature rise and localized hot spot in handheld equipment. Summit’s proprietary TurboChargeTM mode allows a 750mA charge current from a 500mA USB port, resulting to significantly reduced charge times.

Charge control includes qualification, trickle-charge, pre-charge, constant current/constant voltage, and termination/safety settings that are fully programmable via a serial I2C/SMBus making the device truly
a flexible solution. Fast charge current level (one or five unit loads) can be set via I2C or an input pin (USB500/100).
