SMB138B規(guī)格書(shū)詳情
INTRODUCTION
The SMB138 is a programmable single-cell lithium-ion/lithium-polymer battery charger designed for a variety of portable applications. The device provides a simple and efficient way to charge high-capacity LiIon batteries via a USB or AC adapter input. Unlike conventional devices, the SMB138’s high-efficiency, switch-mode operation eliminates the thermal problems of conventional linear solutions. Also the buck converter architecture effectively multiplies the input current to increase charge rate for the Li+ cell and uses current limited supplies like USB more efficiently. The SMB138 also supports USB On-the-Go devices by providing the required USB-OTG +5V power supply using the Li-Ion battery as a source.
FEATURES & APPLICATIONS
? USB or AC input with programmable input current limiting
? Up to 1.25A continuous charging current from AC adapter
? Up to 750mA charging current from 500mA USB port using automatic TurboCharge? mode
? +4.35 to +6.2V input voltage range (+16V tolerant)
? Two product options:
o SMB138A: charger off until I2C command initiation, enable/disable control via I2C
o SMB138C: charger powers up in charging mode, enable/disable control via I2C
? USB “On-the-Go” Power support for USB OTG enabled devices (+5V reverse output @ 200mA)
? Reverse current blocking (<5uA)
? High-efficiency 3MHz voltage-mode step-down regulator
? Integrated frequency compensation
? Internal power MOSFETs and precision current sensing
? High-accuracy float voltage regulation: 1
? Thermal regulation (current foldback)
? Trickle charging
? Pre-charge and complete-charge (36/240min) safety timers
? Digital programming of all major parameters via I2C interface
o Fast charge voltage threshold, float voltage
o Pre-charge, fast charge, termination current
? Status register monitors and flags charger operation
o Charge in-progress/termination
o Charge timer fault
o OC/UV/OV detection/shutdown
? uCSP-19 lead-free package (0.4mm ball pitch)
Applications
? 2.5/3/3G+ GSM/CDMA/WCDMA Phones
? Smartphones/PDAs
? Portable Media Players
? Portable GPS Terminals
