The On Semiconductor CAT3224HV3-GT2 is a versatile LED driver designed for high-current applications, particularly those requiring powerful LED flash capabilities. It integrates a dual-mode charge pump capable of charging a dual-cell supercapacitor to a nominal voltage of 5.4V, while an active balance control circuit ensures cell voltage matching.
This device delivers up to 4A LED flash pulses, significantly exceeding the peak current capabilities of typical Li-ion batteries. It offers two channels, each capable of 2A in flash mode and 200mA in torch mode. The charge current limit is adjustable up to 1000mA, and both flash and torch mode currents can be set independently using external resistors. A built-in safety timer automatically terminates flash pulses exceeding 300ms.
Protection features include thermal shutdown, overvoltage protection, and over-current limiting. The CAT3224HV3-GT2 is packaged in a compact 3mm x 3mm, 16-pad TQFN package, making it suitable for space-constrained designs. It operates within a temperature range of -40°C to 85°C and supports input voltages from 2.5V to 5.5V.
Applications include high-power LED flash for cameras and other devices requiring intense, short-duration light bursts. The device also supports continuous supercapacitor charging and features a "zero" current shutdown mode for power efficiency.
