HQC offers power management buck/boost converters. HQC provides high-efficiency, small-sized management products with integrated low Rds(on) MOSFETs, fast transient response, low ripple, low noise, and low EMI. HQC PMIC solutions support applications with 3.3V, 5V, and 12V and greatly simplify the system power design process by eliminating the need for external discrete components, reducing overall system size, cost and time-to-market.
HQC offers protection ICs for lithium-ion based batteries. Our battery protection ICs to detect a variety of fault conditions including overvoltage, undervoltage, discharge overcurrent and short circuit in single-cell and multi-cell batteries.
HQC USB power switch ICs manage USB power rails by creating an electrical connection from the source to the load in a circuit, and provide protection against over-voltage, over-current and short-circuit occurrences.
HQC’s high-performance, low-profile battery management ICs enable ultra-compact backup battery packs and standalone chargers. Each device integrates all required functions, including a switching charger, boost converter, and LED indication, and supports a complete charging cycle with preconditioning, constant-current fast charge, and constant-voltage termination.
