Analog Devices Inc. MAX20430EVKIT Evaluation Kit provides a fully assembled and tested application circuit for the MAX20430 Four-Output Power-Management IC (PMIC). The Evaluation Kit can test all outputs to full load within the normal operating input range of 3.5V to 36.0V. The MAX20430 PMIC features two modes of watchdog operation, challenge/response, and simple windowed mode, which can also be disabled for simplified evaluation.
The MAX20430EVKIT Evaluation Kit is designed to be used with an I2C interface, such as the MAX32625PICO Board, and PC software that can read and write to the device, such as SimpleI2C. The IC has a Packet-Error Checking (PEC) feature that is enabled by default. This option can be disabled through CONFIG1 register 0x01, bit 0 (PECE). In order to write to a register when the PEC is enabled, the I2C transaction must be followed by a PEC byte. The SimpleI2C software simplifies this process by providing a PEC enable setting.
