  • Page 2: Hardware Configuration

    UM3410 Hardware configuration Hardware configuration Setting The connector J1 (4 pins) on the bottom right corner of the board allows you to set up the power supply voltage and also to read the current sense output voltage and the comparator output. The connector J4, on the top of the board is used to set the input of the TSC20x comparator.

  • Page 3: Daughter Board Connection

    UM3410 Hardware configuration Daughter board connection STEVAL-AETKT3V1 evaluation kit allows you to use 3 different current sense amplifiers, and each of them can be connected on the mother board STEVAL-AET31V1B as suggested by the Figure 3. Daughter board connection. Figure 3.

  • Page 4: Comparator

    UM3410 Comparator Comparator The TSC20x family integrates an open-drain comparator, which can be useful for an overcurrent protection function. It is generally recommended to use a 4.7 kΩ pull-up resistance on the output. The voltage applied on the pull-up resistance must be in the 2.7 to 18 V range, regardless of the V .

    UM3410 Comparator Or you can use the two resistors R3 and R4 to have a tension divider bridge directly connected to the output current sensor. Here the two resistors have the same value (1 KΩ) but other values can be used to adapt the voltage in CMP pin for your application.

  • Page 6: Comparator Power-On Reset

    UM3410 Comparator Comparator power-on reset The TSC20x's comparator integrates a power-on reset, allowing it to have a defined output state. The TSC20x comparator has an open drain output, so while the V power supply is lower than 1.5 V, the output is ever equal to V .
