PRODUCTION DATA
COMPONENT | DESCRIPTION | PURPOSE |
---|---|---|
TVS | SMBJ60CA (optional) | Filter voltage transients coming from battery (ISO7637-2). |
CVS | 220nF (optional) | Better EMI performance. |
CIC | 100nF | Minimal amount of capacitance on input for EMI mitigation. |
CBULK | 10µF (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 | 10kΩ–50kΩ | Set current limit threshold. |
RSNS | 1k | Translate the sense current into sense voltage. |
CFILTER | 100pF | Coupled with RPROT on the SNS line creates a low pass filter to filter out noise going into the ADC of the MCU. |
CVOUT | 22nF | Improves EMI performance, filtering of voltage transients. |
RGND | 4.7kΩ | Stabilize GND potential during turn-off of inductive load. |
DGND | MSX1PJ | Keeps GND close to system ground during normal operation. |
