Component | Description | Purpose |
|---|---|---|
TVS | SMBJ39CA (optional) | Filter voltage transients coming from battery (ISO7637-2) |
CVBB | 220 nF (optional) | Better EMI performance |
100 nF, 1 nF (optional) | Further optimizes EMI performance | |
CIC | 100 nF | Minimal amount of capacitance on input for EMI mitigation |
CBULK | 10 uF (optional) | There to hold the rail for the LDO; however, helps to filter voltage transients on supply rail. Not a requirement. |
RPROT | 5 kΩ | Protection resistor for microcontroller and device I/O pins |
RILIM | 7 kΩ – 70 kΩ | Set current limit threshold |
RSNS | 1kΩ | Translate the sense current into sense voltage. |
CFILTER | 100 nF | Coupled with RPROT on the SNS line creates a low pass filter to filter out noise going into the ADC of the MCU |
CVOUT | 22 nF | Improves EMI performance, filtering of voltage transients |
1 nF, 1 nF (optional) | Further optimizes EMI performance | |
RGND | 1 k? | Stabilize GND potential during turn-off of inductive load |
DGND | BAS21 Diode | Keeps GND close to system ground during normal operation |
