LTM8061 is a high efficiency 32V, 2A µModule® standalone Li-Ion battery charger. It provides a constant-current/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 time-based termination scheme is desired. Once charging is terminated, this device 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. It is widely used in applications such as industrial handheld instruments, 12V to 24V automotive and heavy equipment, professional video/camera chargers etc.
- Float voltage is 8.4 typical at (TA = 25°C, RUN = 2V)
- User-selectable charge termination: C/10 or onboard termination timer
- Dynamic charge rate programming/soft-start pin
- Programmable input current limit
- Optional reverse input protection
- NTC resistor temperature monitor
- 0.5% float voltage accuracy
- Bad-battery detection with auto-reset
- Operating temperature is -40°C to 125°C
- Package style is 77-lead LGA
