PowerPath™ Operatio Instant-On Operation with Discharged Battery The LTC®4015 is a complete synchronous buck controller/
charger with pin-selectable, chemistry specific charging
and termination algorithms. n The LTC4015 can charge Li-Ion/Polymer, LiFePO4, or leadacid batteries. Battery charge voltage is pin selectable and
I2C adjustable. Input current limit and charge current can
be accurately programmed with sense resistors and can
be individually adjusted via the I2C serial port. A digital
telemetry system monitors all system power parameters. …
