5.2
The DEFAULT pin is an active high input. A weak pull-up current (typical 15 μA) on this
pin ensures a defined level when this pin is not connected (e.g. open pin). An active high
signal on the DEFAULT pin sets the commanded current for both channels to 0 mA, and
resets all programmable registers to their default values. Any SPI commands that are
received while the DEFAULT pin is high will be ignored, and the SO pin will remain in a
high impedance state.
The fault register bits are not cleared when the Default pin is asserted.
Upon coming out of default mode, the commanded current will remain at 0 mA, device
off, and the programmable registers will remain at their default values.
The DEFAULT pin must be asserted high whenever the voltage on the pin
than the minimum
specifications (see table below) may not be met. The diagnostic functions are not
operational when the
The TEST pin is an active high pin. This pin must be connected directly to ground in the
application, as it is only used for IC test purposes. A passive pull-down resistor in the
device ensures a logic low value when the pin is not connected.
