P9180A-I0NHGI8

Power Management - Specialized Overview

The P9180A-I0NHGI8 is a programmable, multi-channel power management integrated circuit (PMIC) from the Renesas P9180 series. It features a 4.5V to 5.25V input voltage range and integrates seven programmable buck converters, five of which include built-in power FETs. The device also includes seven general-purpose LDOs, supporting source/sink VTT configurations. Communication is handled via a high-speed I2C interface and an SVID interface compliant with the IMVP8 protocol for VCC, VNN, and optional VDDQ rails. Additional subsystems comprise a 10-bit ADC, 15 programmable GPIOs, and 12 programmable enable outputs. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 100-lead, 9x9 mm double-row GQFN package.
