Description
Active High Output. This pin is asserted when there has been no SPI activity on the interface pins for a
predetermined time. See the Device Features section for more information.
Active Low Output. This pin is asserted low when an open circuit in current mode is detected, a short circuit in
voltage mode is detected, a PEC error is detected, or an overtemperature is detected (see the Device Features
section). Open-drain output.
Power-On Condition. This pin determines the power-on condition and is read during power-on or, alternatively,
after a device reset. If POC = 0, the device is powered up with the voltage and current channels in tristate mode.
If POC = 1, the device is powered up with a 30 kΩ pull-down resistor to ground on the voltage output channel,
and the current channel is in tristate mode.
Hardware Reset, Active Low Input.
Positive Analog Supply. The voltage range is from 9 V to 33 V.

DC-to-DC Compensation Capacitor. Connect a 10 nF capacitor from this pin to ground. Used to regulate the
feedback loop of the Channel A dc-to-dc converter. Alternatively, if using an external compensation resistor,
place a resistor in series with a capacitor to ground from this pin (see the DC-to-DC Converter Compensation
Capacitors and the AI
information).
