描述
The ISL6115AEVAL1Z evaluation board is default provided as a +12V high-side switch controller with the CR level set at 2.5A.
Bias and load connection points are provided along with test points for each IC pin. With J1 installed the ISL6115A will be biased from the +12V supply (VIN) being switched. Connect the load to VLOAD+. The PWRON pin pulls high internally enabling the ISL6115A if not driven low via PWRON test point or J2.
With R3 = 1.24kΩ, the CR Vth is set to 24.8mV, and with the 10mΩ sense resistor (R1), the ISL6115AEVAL1Z has a nominal CR level of ~2.5A. The 0.01µF delay time to latch-off capacitor results in a nominal 1ms before latch-off of output after an OC event.
Reconfiguring the ISL6115AEVAL1Z board for a higher CR level can be done by changing the RSENSE and/or RISET resistor values as the provided FET is rated for a much higher current.
