Table 2-4 Jumper and LED Descriptions
Jumper Label Description
J5 LPM 1-2 position forces the device to lower power mode.
J6 SCP_TEST When driven low to high, short-circuit test diagnostics are performed. Position 1-2 drives signal to ground.
J7 TMR Retry behavior selection. Positions 1-2 set the retry duration to 1.2s (47nF capacitor), positions 3-4 set the duration to 12s (470nF capacitor), position 5-6 set the device to latch-off via 100kOhm resistor.
J8 I2T I2T level selection. Positions 1-2 set the level to 150nF capacitor and positions 3-4 set the level to 470nF capacitor. Check the design calculator for the exact significance of these values.
J9 IOC Overcurrent protection selection. Positions 1-2 set the limit to 15.8A (24.6kOhm resistor) and positions 3-4 set the limit to 36.2A (4.7kOhm resistor).
J10 Ground diode bypass.
D8 D8 Fault indicator. LED turns ON for under-voltage fault, short-circuit fault, I2t, and during SCP comparator diagnosis.
