SLIS178B October 2017 – January 2018 TPS92830-Q1
The TPS92830-Q1 device has an internal power-on-reset (POR) function. When power is applied to IN, the internal POR holds the device in the reset condition until VIN reaches V(POR_rising).
When the supply rises above POR threshold V(POR_rising), the charge pump starts working. The maximum gate-drive voltage is determined by the charge-pump voltage between CPOUT and IN.
