ADP1043A
VDD
When VDD is applied, a certain time elapses before the part is
capable of regulating the power supply. When the VDD rises
above the power-on reset and UVLO levels, it takes approxi-
mately 20 μs for VCORE to reach its operational point of 2.5 V.
The EEPROM contents are then downloaded to the registers.
The download takes an additional 25 μs (approximately). After
the EEPROM download, the ADP1043A is ready for operation.
If the ADP1043A is programmed to power up at this time, the
soft start ramp begins.
VDD/VCORE OVLO
The ADP1043A has built-in overvoltage protection (OVP) on
its supply rails. When the VDD or VCORE voltage rises above
the OVLO threshold, the response can be programmed. This
circuit can be set to be ignored, but it is recommended that the
user not program the OVP circuit to be ignored.
POWER GOOD
The ADP1043A has two power-good pins. The PGOOD1 pin
and fault flag are set when any of the following conditions are
out of range: power supply, CS1 fast OCP, CS1 accurate OCP,
CS2 accurate OCP, UVP, local OVP, or load OVP.
The PGOOD2 pin and fault flag are set when any flag is set:
power supply, OrFET, CS1 fast OCP, CS1 accurate OCP, CS2
accurate OCP, voltage continuity, UVP, accurate OrFET disable,
ACSNS, external flag (FLAGIN), VCORE OV, VDD OV, local
OVP, load OVP, OTP, CRC fault, and EEPROM unlocked.
If Register 0x2D[3] is set, PGOOD2 looks only at the flags that
are not programmed to be ignored.
The PGOOD2 pin can also be used as an interrupt pin to notify
a host controller that a flag has been set. The polarity of the
PGOOD1 and PGOOD2 pins is configured as active low.
