LTC4162-S 35V/3.2A Lead-Acid Step-Down Battery Charger with PowerPath and I2C Telemetry DESCRIPTION FEATURES Lead-Acid Battery Charger with Absorb and Equalize nn Wide Charging Input Voltage Range: 4.5V to 35V nn High Efficiency Synchronous Operation nn 16-Bit Digital Telemetry System Monitors V BAT, IBAT, RBAT, TBAT, TDIE, VIN, IIN, VOUT nn Charges 6V, 12V, 18V and 24V Lead-Acid Batteries nn Input Undervoltage Charge Current Limit Loop nn Input MPPT for Solar Panel Inputs nn Input Current Limit Prioritizes System Load Output nn Low Loss PowerPath™ nn Instant-On Operation with Discharged or Missing Battery nn Temperature Controlled Charging nn Pin Compatible with Li-Ion and LiFePO Versions 4 The LTC®4162-S is an advanced monolithic synchronous step-down switching battery charger and PowerPath™ manager that seamlessly manages power distribution between input sources such as wall adapters, backplanes, solar panels, etc., and a lead-acid battery. APPLICATIONS The power path topology decouples the output voltage from the battery allowing a portable product to start up instantly under very low battery voltage conditions. nn Medical Instruments USB-C Power Delivery nn Industrial Handhelds nn Ruggedized Notebook nn Tablet Computers nn A high resolution measurement system provides extensive telemetry information for circuit voltages, currents, battery resistance and temperature which can all be read back over the I2C port. The I2C port can also be used to configure many charging parameters including charging voltages and currents, termination algorithms and numerous system status alerts. The LTC4162-S can charge 6V, 12V, 18V and 24V leadacid batteries with as much as 3.2A of charge current. The LTC4162-S is available in a thermally enhanced 28pin 4mm × 5mm × 0.75mm QFN surface mount package. nn All registered trademarks and trademarks are the property of their respective owners.
