Product Overview

DC1645A-C demonstration boards feature the LTM8061, a 32V, 2A uModule Li ion battery charger. Operating from a 12V to 32V input source, the demo circuit charge dual cell Li ion battery packs to float voltages of 8.2V. It provides a constant current or constant voltage charge characteristic, with maximum charge current up to 2A. A precondition feature trickle charges a depleted battery, and bad battery detection provides a signal and suspends charging if a battery does not respond to preconditioning. It can be configured to terminate charging when charge current falls to one-tenth the programmed maximum current or to use an internal timer if a timebased termination scheme is desired. Once charging is terminated, it enters a low current standby mode. An auto restart feature starts a new charge cycle if the battery voltage drops 2.5% from the float voltage, or if a new battery is inserted into a charging system. Jumper on board allows for easy selection of timer charge termination.
  • Dynamic charge rate programming/soft start pin
  • Programmable charge current
  • User selectable charge termination
  • Optional reverse input protection
  • NTC resistor temperature monitor
  • Bad battery detection with auto reset
