Product Overview

The LTC4100EG#PBF is a Smart Battery Charger Controller that dramatically simplifies construction of an SBS compliant system. It implements a Level 2 charger function whereby the charger can be programmed by the battery or by the host. A SafetySignal on the battery being charged is monitored for temperature, connectivity and battery type information. The SMBus interface remains alive when the AC power adapter is removed and responds to all SMBus activity directed to it, including SafetySignal status. The charger also provides an interrupt to the host whenever a status change is detected. Charging current and voltage are restricted to chemistry specific limits for improved system safety and reliability. Limits are programmable by two external resistors. Additionally, the maximum average current from the AC adapter is programmable to avoid overloading the adapter when simultaneously supplying load current and charging current.
  • Single chip smart battery charger controller
  • 100% Compliant (Rev. 1.1) SMBus support allows for operation with or without host
  • SMBus accelerator improves SMBus timing
  • Wide output voltage range (3.5 to 26V)
  • Hardware interrupt and SMBAlert response eliminate interrupt polling
  • High efficiency synchronous buck charger
  • 0.5V Dropout voltage, >98% maximum duty cycle
  • AC adapter current limit maximizes charge rate
  • ±0.8% Voltage accuracy, ±4% current accuracy
  • Up to 4A charging current capability
  • 10-Bit DAC for charge current programming
  • 11-bit DAC for charger voltage programming
  • User-selectable overvoltage and over-current limits
  • High noise immunity SafetySignal sensor
