Key Features
- Universal battery chemistry support — charges Lead-Acid, Li-Ion, Li-Polymer, NiCd, and NiMH batteries from a single programmable IC
- 2A maximum charge current with current-mode control enables fast charging of portable battery packs while maintaining precise CC/CV regulation
- Wide 2.7V to 25V input voltage range in an 8-pin DDPAK power package suits USB, wall-adapter, and automotive input sources
Applications
The LT1513-2CR#TRPBF is designed for portable consumer electronics chargers, power banks, and embedded charging systems that must support multiple battery chemistries from a single PCB design. Its 2A charge current and 25V maximum input range make it suitable for automotive accessory chargers, industrial handheld tools, and medical portable devices where the battery type may vary across product variants. Current-mode control simplifies feedback loop compensation and enables fast transient response during load changes in the charging circuit.

Frequently Asked Questions
What battery chemistries can the LT1513-2CR#TRPBF charge, and how is the charge voltage programmed for each?
The LT1513-2CR#TRPBF supports Lead-Acid, Li-Ion, Li-Polymer, NiCd, and NiMH battery chemistries. The output charge voltage is set by an external resistor divider network connected to the feedback pin, allowing the designer to program the termination voltage appropriate for each chemistry — for example 4.2V per cell for Li-Ion, 2.4V per cell for NiCd or NiMH, and 2.3V to 2.45V per cell for Lead-Acid — without changing the IC.
What is the maximum charge current of the LT1513-2CR#TRPBF, and how is it set in the application circuit?
The LT1513-2CR#TRPBF delivers up to 2A of charge current. The charge current is set by an external sense resistor connected between the SENSE pin and the battery terminal. By selecting the sense resistor value, designers can program the constant-current phase to any value from a few hundred milliamps up to 2A, enabling the same IC to be used in applications ranging from small single-cell packs to larger multi-cell battery assemblies.
What input voltage range does the LT1513-2CR#TRPBF support, and which power sources are compatible?
The LT1513-2CR#TRPBF accepts input voltages from 2.7V minimum to 25V maximum, with a nominal design point of 5V. This range covers USB 5V adapters, 12V automotive systems, 15V laptop power bricks, and 19V to 20V wall adapters, allowing a single circuit design to be powered from virtually any common DC power source used in consumer, industrial, or automotive charging applications.
What package does the LT1513-2CR#TRPBF use, and why is thermal management important at 2A charge current?
The LT1513-2CR#TRPBF is housed in an 8-pin DDPAK (7+Tab) surface-mount power package, which includes an exposed metal tab on the underside for soldering to a PCB copper thermal plane. At 2A charge current with a 12V input charging a 4.2V Li-Ion cell, the IC can dissipate several watts. Proper solder connection of the tab to a copper pour area of at least 1 square inch is required to keep the junction temperature below 125°C and maintain safe, reliable charging operation.
