Power-supply Fail

If undervoltage is detected at pin VS, the power-supply fail bit (PSF) in the output register is set and all outputs are disabled.

To detect an undervoltage, its duration has to last longer than the undervoltage detection delay time t_dUV. The outputs are

enabled immediately when the supply voltage returns to the normal operational value. The PSF bit stays high until it is reset

by the SRR bit in the input register.

Open-load Detection (Available for H-Bridge Configuration only)

If the open-load detection bit (OLD) is set to low, a pull-up current for each high-side switch of typically 2.5mA and a pull-

down current for each low-side switch of typically 9mA is turned on (open-load detection current IOut1-3).

The open load condition of all the outputs is indicated in the SPI output register bit 1-6.

Activating an output stage with the OLD bit set to low disables the open-load function for this output.

Operating open load and short circuit detection in H-Bridge configuration requires the following command sequence:

Step #1

a. Low side check

Input: HSx = 0, LSx = 1, HSy = 0, LSy = 0, OLD = 0

b. Feedback:

LSy = 1 indicates “Motor connected”

LSy = 0 indicates “Motor connection fail”, open load

Step #2

a. High side check

Input: HSx = 1, LSx = 0, HSy = 0, LSy = 0, OLD = 0

b. Feedback:

HSy = 1 indicates “Motor connected”

HSy = 0 indicates “Motor connection fail”, open load

The maximum H-bridge load resistance for proper load detection is 170.

Both conditions step #1 and #2 need to be fulfilled.
