Description
Power Supply On Input. This signal is referred to DGND. This is the hardware PSON control signal. It is recom-
mended that a 1 nF capacitor be included from the PSON pin to DGND for noise debounce and decoupling.
Flag Input. An external signal can be input at this pin to generate a flag condition.
Power-Good Output (Open Drain). This signal is referred to AGND. This pin is controlled by the PGOOD2 flag.
This pin is set if any flag is set.
Power-Good Output (Open Drain). This signal is referred to AGND. This pin is controlled by the PGOOD1 flag.
This pin is set if any of the following are out of range: power supply, CS1 fast OCP, CS1 accurate OCP, CS2
accurate OCP, UVP, local OVP, or load OVP.
Share Bus Output Voltage Pin. Connect this pin to 3.3 V through a 2.2 kΩ resistor. When configured as a digital
share bus, this pin is a digital output. This signal is referred to AGND.
Share Bus Feedback Pin. Connect this pin to the SHAREo pin. This signal is referred to AGND.
Digital Ground. This pin is the ground for the digital circuitry of the ADP1043A. Star connect to AGND.
Output of 2.5 V Regulator. Connect a 100 nF capacitor from this pin to DGND.
Positive Supply Input. Range is from 3.1 V to 3.6 V. This signal is referred to AGND.
Thermistor Input. A 100 kΩ thermistor is placed from this pin to AGND. This signal is referred to AGND.
Address Select Input. Connect a resistor from ADD to AGND. This signal is referred to AGND.
Resistor Input. This pin sets up the internal voltage reference for the ADP1043A. Connect a 49.9 kΩ resistor
(±0.1%) from RES to AGND. This signal is referred to AGND.
Inverting Remote Voltage Sense Input. There should be a low ohmic connection to AGND. The resistor divider
on this input must have a tolerance specification of 0.5% or better to allow for trimming.
Noninverting Remote Voltage Sense Input. This signal is referred to VS3?. Use 0.1% resistors as the resistor
divider to connect this circuit. The resistor divider on this input must have a tolerance specification of 0.5%
or better to allow for trimming.
The ADP1043A has an exposed thermal pad on the underside of the package. For increased reliability of the
solder joints and maximum thermal capability, it is recommended that the pad be soldered to the PCB
ground plane.
