SLM6500

Sola IC SLM6500 2A Synchronous Buck Li-Ion Battery Charger _________________Description The SLM6500 is a 2A single cell Li-ion battery charger applied for 5V wall adapters. It utilizes 1.5MHz synchronous buck converter topology to reduce power dissipation and therefore reaches a high efficiency up to 90%. The SLM6500 includes complete charge termination circuitry, automatic recharge, and a ±1% 4.2V float voltage. It also has other features include output short-circuit protection, battery temperature monitor, overheating protection, and no blocking diode is required. The SLM6500 is available in SOP8/MSOP8 package with heat sink. Its few external component count makes the SLM6500 a high-efficient battery charger ideally suited for portable applications. _____ Absolute Maximum Ratings  Vcc：-0.3V~8V  BAT：-0.3V~7V  LX：-0.3V~7V  VS：-0.3V~7V  NCHRG：-0.3V~8V  NSTDBY：-0.3V~8V  TS：-0.3V~8V  BAT Short-Circuit Duration：Continuous  Maximum Junction Temperature：145℃  Operating Temperature Rang: -40℃~85℃  Storage Temperature Range：-65℃~125℃  Lead Temperature（Soldering, 10 sec） 260℃ _____________________Features  1.5MHz Fixed Switching Frequency  High Efficiency up to 90%  2.5A Maximum Charge Current  No External MOSFET or Blocking Diode Required  Preset 4.2V Charge Voltage with ±1% Accuracy  Automatic Recharge  Charge State Pairs of Output, No Battery and Fault Status Display  C/10 Charge Termination  140uA Supply Current in Shutdown  2.9V Trickle Charge  Soft-Start...
