1. Input circuit
- To reduce input signal noise by high speed switching, the RIN and CIN filter circuit should be mounted. (100Ω, 1nF)
- CIN should be placed as close to VSS pin as possible.
2. Itrip circuit
- To prevent protection function errors, CITRIP should be placed as close to Itrip and VSS pins as possible.
3. VFO circuit
- VFO output is an open drain output. This signal line should be pulled up to the positive side of the 5V/3.3V logic
power supply with a proper resistor RPU.
- It is recommended that RC filter be placed as close to the controller as possible.
4. VB-VS circuit
- Capacitor for high side floating supply voltage should be placed as close to VB and VS pins as possible.
5. Snubber capacitor
- The wiring between CIPOS™ Mini and snubber capacitor including shunt resistor should be as short as possible.
6. Shunt resistor
- The shunt resistor of SMD type should be used for reducing its stray inductance.
7. Ground pattern
- Ground pattern should be separated at only one point of shunt resistor as short as possible.
