5.4.3
The OLSG fault bit is set under the following conditions.
Operating Condition #1
The average current command is > 50 mA (with 1 Ω sense resistor) and the low-side
driver is ON (solenoid current is increasing).
The OLSG (open load/short to ground) fault bit will be set if the low-side transistor
remains on for a time greater than the on state open sense time
Characteristics” on Page
Operating Condition #2
The average current command is > 50 mA (with 1 Ω sense resistor) and the low-side
driver is OFF.
The OLSG fault bit is set if the voltage on the NEGx pin is less than the NEG pin OLSG
threshold voltage
greater than the NEG pin OLSG delay time
Item
Operating Condition #3
The average current command is < 50 mA (with a 1 Ω sense resistor) and the fault typing
bit = 0.
The OLSG (open load/short to ground) fault bit will be set if the POS pin voltage is less
than the off state open load threshold
