SLUSDL4 February 2020 TPS59632-Q1
PRODUCTION DATA
The TPS59632-Q1 device initializes when all of the supplies rise above the UVLO thresholds. This function is also know as a cold boot. The device then reads all of the various settings (such as frequency and overcurrent protection). This process takes less than 1.2 ms. During this time, the VSR initializes to the BOOT voltage. The output voltage rises to the VSR level when the EN pin (enable) goes high. Once the BOOT sequence completes, PGOOD is HIGH and the I2C interface can be used to change the voltage select register (VSR). The current VSR value is held when EN goes low and returns to a high state This function is also known as a warm boot.
