I am using the TPS2HB16AQPWPRQ1 WITH THE HSS-MOTHERBOARDEV. Although I configure the board to disable the switch at a particular current (for example 7 amps or 3 amps) it does not disable until it goes into thermal shut down I have tried everything to get it to work but have been unsuccessful.
The HSS-MOTHERBOARDEV configuration is as follows: Vbb = 12.0 volts, LATCH Enabled, Channel 1 enabled, Channel 2 disabled, CH1 Current selected for SNS, Output DIAG Enabled, R_ILIM is connected between TP17 and Vbb.
To test the current limit feature the following R_ILIM resistors were selected (separate tests): R_ILIM = 14.7 kohms for a current limit of approx 7 amps R_ILIM = 20.0 kohms for a current limit of approx 5.1 amps.
The load used: Hauman Inc. EL-150, Electronic Load Load connected to VOUT1 and GND
Test procedure: The Electronic Load current was increased past the anticipated current limit, first for the 7 amp current limit setup then for the 5.1 amp current limit setup. In both tests the TPS2HB16AQPWPRQ1 device did not disable the the switch. Even when the load current was increased to 12 amps the device did not disable.
