Linear Technology LT3652HV

The LT3652HV 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 18V can be programmed with a resistor divider. The LT3652HV employs an input voltage regulation loop, which reduces charge current if the input voltage falls below a programmed level, set with a resistor divider.

DESCRIPTION

The LT®3652HV is a complete monolithic step-down battery charger that operates over a 4.95V to 34V input range. When the LT3652HV is powered by a solar panel, the input regulation loop is used to maintain the panel at peak output power. The LT3652HV can be conﬁgured to terminate charging when charge current falls below 1/10 of the programmed maximum (C/10). Once charging is terminated, the LT3652HV 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 LT3652HV 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.
