Roll over image to zoom in

The PCA9451A is a general purpose single chip power management IC (PMIC) designed to support different microcontrollers and microprocessors for different applications for the consumer and industrial markets. The PCA9451A provides an out-of-the-box power supply solution to support i.MX 93 family processors.

The device provides six high efficiency step-down regulators, three LDOs, one 400 mA load switch, 2-channel level translator and 32.768 kHz crystal oscillator driver.

This PCA9451A-EVK board provides full access to all the features in the PCA9451A device. The evaluation kit comes with a FTDI cable used as a communication interface between I²C and USB to have control of the PMIC's configuration registers using the PCA9451A GUI software.
