The BQ25792RQMR is suitable for fast-charging devices, industrial handheld terminals, and energy storage equipment, providing a high-power-density and highly integrated solution.
2. Product Features Of BQ25792RQMR
High Power Density: All power stages and compensation networks are integrated within the BQ25792RQMR, requiring only a few external components to achieve 5 A charging.
Ultra-Wide Input: Operates from 3.6 V to 24 V with an absolute maximum of 30 V, enabling the BQ25792RQMR to directly connect to diverse power sources such as USB-C PD, car adapters, and solar panels.
High-efficiency conversion: With selectable switching frequencies of 750 kHz or 1.5 MHz, the BQ25792RQMR achieves efficiency as high as 96.5% under 20 V input and 16 V/3 A charging conditions.
Bidirectional OTG: Adjustable output from 2.8 V to 22 V with 10 mV steps, the BQ25792RQMR supports 3.32 A reverse output, easily driving USB-PD PPS devices.
Smart protection: Integrated overvoltage, overcurrent, short-circuit, thermal shutdown, and safety timer protections ensure system safety and reliability.
Ultra-low power consumption: IQ = 21 µA when powered by battery alone, and only 600 nA in shutdown mode, significantly extending standby time.
Flexible interface: I²C or standalone dual-mode operation, with an integrated 16-bit ADC for real-time monitoring of voltage, current, and temperature.
