LT LT3652EMSE#TRPBF

多化学2A-40°C ~ 125°C（TJ）

Overview

The LT3652EMSE is a complete monolithic step-down battery charger that operates over a 4.95V to 32V input voltage range. The LT3652EMSE provides a constant-current/constant-voltage charge characteristic, with maximum charge current externally programmable up to 2A. The charger employs a 3.3V float voltage feedback reference, so any desired battery float voltage up to 14.4V can be programmed with a resistor divider.

The LT3652EMSE can be configured to terminate charging when charge current falls below 1/10 of the programmed maximum (C/10). Once charging is terminated, the LT3652EMSE enters a low-current (85μA) standby mode. An auto-recharge feature starts a new charging cycle if the battery voltage falls 2.5% below the programmed float voltage. The LT3652EMSE also contains a programmable safety timer, used to terminate charging after a desired time is reached. This allows top-off charging at currents less than C/10.
