I want to use the TLI4971-A050T5-U-E0001 in Single-Ended Output Mode.
The datasheet says "The pre-configured output mode is set to semi-differential mode." "The sensor can be reprogrammed into single-ended operating mode or fully-differential mode by user without any recalibration of the device."
Do I need to reprogram the device? If so, what is the cheapest way to do that for a one-off scenario? If I follow the strategy in Current Sensor TLI4971 Programming Guide and User Manual, "1.2 In-circuit programming with external Programmer", what would be a good choice for the external programmer? Can the TLI4971_MS2GO program an external chip?
Solved! Go to Solution.

Hi @CaKu_4284131 ,
For changing the output configuration you can use the MS2GO which temporarily changes the output configuration. After power down the initial configuration will be present. --> cheapest solution
For a permanent change you need to go for a programmer:
(1) in-circuit programming: 1 pin for control of Vdd / 1 pin for communication on Aout / 1 pin for applying 20V programming voltage on OCD2
(2) external in-circuit-programmer: same pins as in-circuit but through a connector on the pcb
(3) external programming in dedicated setup
external programmers can be bought at Infineon (laboratory usage) or at our partner CGS (industrial grade including 24/7 support)
Kind regards,

Thanks, Deepa and Klaus.
Ideally, what I'm looking for is something ratiometric to the Vref of the ADC in my (3.3 V) MCU. It doesn't look like I can get that with Semi-Differential Output Mode, and it doesn't look like programming the TLI4971 is practical for small volumes.
