Hi,
Kindly support for below queries regarding TPS4H000AQPWPRQ1.
- Can we make all 04 output channels ON simultaneously with 0.5Amp normal DC load current each channel ? i.e. total Normal DC load current through High Side
switch will be 2Amp ( 4 x 0.5A).
2.Output channels pins are ESD protected or not? ( for Contact Discharge@ +/-4KV & Air discharge@ +/-8KV). If not, what are TI recommendation to protect device from ESD ?
3.We will not use any diagnostic status pin/feature. In this case, for Short to GND and Overload fault condition, device will go in thermal shutdown mode & becomes OFF. When we remove fault condition i.e. overload or short to GND condition, then device automatically recovers. Is it OK?
4.We will not use any diagnostic status pin/feature. In this case, how Open-load Detection feature used ?
5.There will be isolation between Digital -Microcontroller section and High Side Switch section. In this case there should be two separate individual 5V DC Supplies, one for Microcontroller section & second for High Side switch section. For this we have to use one additional “24V to 5V DC-DC converter power supply” for High Side switch section ( i.e. INx, STx, pins etc..). For this, is there any alternative low cost solution?
Kindly provide feedback ASAP.
