描述

The TPS6521825 is a single chip, power-management IC (PMIC) specifically intended to support the i.MX 8M Mini processor in conjunction with the LP873347 device. The device is characterized across a –40°C to +105°C temperature range, making it suitable for various industrial applications.

Three hysteretic step-down converters are targeted at providing power for the processor core, MPU, and DDRx memory. The default output voltages for each converter can be adjusted through the I2C interface. DCDC1 and DCDC2 feature dynamic voltage scaling to provide power at all operating points of the processor. DCDC1 and DCDC2 also have programmable slew rates to help protect processor components. DCDC3 remains powered while the processor is in sleep mode to maintain power to DDRx memory. Backup power provides two step-down converters for the tamper, RTC, or both domains of the processor if system power fails or is disabled. If both system power and coin-cell battery are connected to the PMIC, power is not drawn from the coin-cell battery. A separate power good signal monitors the backup converters. A battery backup monitor determines the power level of the coin-cell battery.
