The LT1512IS8#PBF from Analog Devices is a versatile 500kHz current mode switching regulator specifically configured for constant-current and constant-voltage battery charging. It is suitable for charging NiCd, NiMH, Lead-Acid, or Lithium Rechargeable Cells, supporting up to 30V and 1A charging current for a single lithium-ion cell.
This device features a ground-referred current sense feedback circuit, simplifying system grounding and allowing charging even when the input voltage is lower than the battery voltage. It offers 1% voltage accuracy, ideal for lithium battery applications, and easily programmable charging current. The 500kHz switching frequency minimizes inductor size, and a 100mV current sense voltage ensures high efficiency.
The LT1512IS8#PBF is available in an 8-SOIC surface mount package. Its operating temperature range is -40°C to 85°C (TA). This component is designed for precision current limited power supplies, constant-voltage/constant-current supplies, and transducer excitation.
Key specifications include a maximum input voltage of 30V and a switch voltage of 40V. The charge current is programmable up to 1A, and it supports charging a single cell with multi-chemistry batteries.
