Description :

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.

Features :

• 4.35 to 6.5V input voltage range

• High-accuracy output voltage regulation: 1%

• Low reverse leakage current

• Status/Fault indicator

• Stability with ceramic capacitors

• Wide range of protection features […]
