* ELEC-299 BMS Current Sense Schematic Library: + IC VREF SERIES 5V 5MA SOT23-5 Changes: - Added LTC6820, transformer and associated passives - Added ADC and buffer op amp - Added VREF IC to library TODO: Finish schematic with current sense amplifier, add tantalum cap to ADC power as per datasheet * ELEC-299 BMS Current Sense Board Schematic Library + IC DCDC ISOLATED 12V-5V 1W 8-SMD 5-LEAD + IC CURRENT AMPLIFIER INA240 TSSOP-8 + CAP TANT 25V 10% 0805 + CAP CER 4.7UF 50V 10% X5R 0805 + CAP CER 0.022UF 50V 10% X7R 0603 + DIODE TVS 170VWM 270VC SMC + RES SHUNT 100UOHM 5% 36W 60MM / IC VREF SERIES 5V 5MA -> IC VREF SERIES 4.096V 5MA PCB Library + IC CURRENT AMPLIFIER INA 240 TSSOP-8 + CAP, TANTALUM 0805 + DIODE, SMC Schematic changes: - Added voltage regulator circuits, and added LDOs - Added INA240 current amplifier with 4.096V reference - Added 2 TVS diodes on the inputs TODO: add LEDs, add TPs, finish schematic for TVS Questions: Should the TVS diodes be connected to HV ground? If so, where does HV ground come from? Should everything be powered off of the LDO? inc 6820 and pullup? * Schematic Library: /Changed RES SHUNT 100UOHM to 2 parts with the connector and linked with 3D model /Linked IC 24BIT ADC with footprint PCB Library: + RES SHUNT 100UOHM 60MM + IC ADC LTC2484 10-DFN - Added test points and LEDs to schematic - Connected bottom of shunt resistor to ISO GND - Created preliminary PCB layout * ELEC-299 Made block diagram embedded * ELEC-299 BMS Current Sense Board Rev 1.2 - Removed one voltage reference IC - Changed 12V-5V DCDC to 12V-12V isolated DCDC - Changed shunt connections to 20 mil - Increased gap between planes to 1mm - Moved INA240 to length match inputs - Generated PDF for schematic and PCB * ELEC-299 BMS Current Sense Rev 1.2 - Deleted buffer op amp - Moved Vref to where the buffer used to be TODO: Finish routing and add thermals for shunt terminals * ELEC-299 BMS Current Sense Rev 1.2 - Finished routing all traces - Changed +5V LDO to 12mil - Added polygon cutout around the thermal pads for current sense - Added stiching vias to shunt terminals - Improved silkscreen - Moved a few test points around to optimize routing * ELEC-299 BMS Carrier Rev 1.3 - Added place holders for PI filters with caps and ferrite beads - Modified schematic to fit new components * ELEC-299 BMS Current Sense Rev 1.4 - Added 2 pads for 0.1" headers for BMS scruteneering - Optimized silkscreen layout - Added extra vias near filtering components to ISO GND - Generated gerbers, NC drill file, PDF and STEP model * ELEC_299 BMS Current Sense - Moved connection between sense resistor and ISO GND, and regenerated all output files * Deleted DIOC1608... LED footprint and changed 3D model of LED, 0603 to a LED instead of a resistor. PcbLib should now be same as the master
