Tool/software:
Hello,
We are designing an electronic circuit breaker using the nicely featured TPS4812-Q1.
We would need some current limit adjustments in the field, using digital potentiometers or some other means. Some questions arise when trying to meet all of the requirements laid out in the datasheet:
- Is the <100uA limit for the I2t Current a hard limit? Will it simply be clamped if the Scaling Factor K is off?
- Can the IMON Scaling Resistors Rset be higher than 500ohms? What drives this limit?
- In Table 5-1, the datasheet mentions that the IOC pin can be driven by an MCU. How is this intended to be done?
Thank you,
