Component |
Description |
Purpose |
|---|---|---|
|
TVS |
SMBJ60CA (optional) |
Filter voltage transients coming from battery (ISO7637-2) |
|
CVS |
220 nF (optional) |
Better 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 |
10k |
Protection resistor for microcontroller and device I/O pins |
|
RILIM |
7k – 70k |
Set current limit threshold |
|
RSNS |
1k |
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 |
|
RGND |
1 k? |
Stabilize GND potential during turn-off of inductive load |
|
DGND |
MSX1PJ |
Keeps GND close to system ground during normal operation |
