TPS65951A1ZGU

TPS65951A1ZGU is a Texas Instruments power-management IC (PMIC) in the TPS6595x family. It provides multiple regulated rails, charge/path management, and system supervision for portable/embedded SoCs, with a focus on smartphones and similar devices. Key features typically include integrated buck regulators and LDOs, power-path/charger control for single- or multi-cell batteries, USB OTG support, sequencing and dynamic voltage scaling, and an I2C/SMBus interface for software control. It combines watchdogs, reset signaling, brownout protection, voltage/current monitoring, and GPIOs for peripherals. The A1 suffix denotes a device revision; ZGU refers to the packaging variant (RoHS, tape-and-reel). Typical applications: mobile devices, development boards, reference designs needing efficient, compact PMIC with programmable rails. For exact specs (input ranges, output voltages, currents, pinout) consult the TI TPS65951A1ZGU datasheet and product page.
