TPS65920A2ZCHR

TPS65920A2ZCHR is a Texas Instruments Power Management IC (PMIC) designed for mobile and embedded systems. It centralizes power for an application processor and peripherals by integrating voltage regulation, sequencing, monitoring, and battery charging in a single device. Typical capabilities include one or more high‑efficiency regulators, general purpose LDOs, load switches, a battery charger and power‑path control, fault protection, and a programmable control interface (I2C/SMBus). It also provides watchdog and interrupt signaling to the host processor and supports power‑on/power‑down sequencing to meet SoC requirements. The A2ZCHR suffix denotes the specific package variant and temperature grade for this part, e.g., lead‑free options and the intended operating range; exact details depend on the lot. Use the TPS65920 datasheet and TI’s product folder for exact rails, currents, pinout, and programming parameters.
