TI AUTOMOTIVE · ENGINEERING GUIDES
From an application question to a specific part
13 guides turn device specifications into checkable selection steps. Establish roles and limits before checking exact OPNs.
BMS and measurement
Separate cell/pack sensing, isolation and communication before comparing channel count, accuracy conditions and migration effort.
Automotive BMS signal chain: cells, current, isolation and communication
Select TI devices by measured quantity, ground domain and fault response, from cell supervision to the battery junction box. Separate communication bridges, current sensing and isolated voltage sensing.
Read guide and checklist →BQ79606A-Q1 vs BQ79616-Q1: cell count, temperature and migration boundaries
An independently sourced comparison of TI's 3–6S and 6–16S cell monitors: Grade 2 versus Grade 1, balancing, interfaces and the checks required for a redesign.
Read guide and checklist →Automotive current-sensing error budgets: shunt, amplifier, ADC and PWM
Compare INA181-Q1, INA241A-Q1 and INA240-Q1 at explicit common-mode, gain and temperature conditions, with worked shunt/ADC range and error budgets, PWM sampling and calibration checks.
Read guide and checklist →Automotive power and supervision
From input envelope to multirail sequencing, verify voltage, current, thermals and the exact OPN.
Automotive power selection: LDO, DC/DC, PMIC and supervisor roles
Select TI automotive power devices by input envelope, load rails, thermal budget and sequencing. Separate converters, controllers, PMICs and supervisors without combining unrelated maximum ratings.
Read guide and checklist →12V/48V automotive power: operating input, transients and absolute maximum ratings
Use TI LDO, boost and wide-input buck examples to distinguish nominal bus voltage from pin stress. Check cold crank, load dump, reverse connection and thermals without treating survival limits as operating points.
Read guide and checklist →TPS6594-Q1 / LP8764-Q1: OPN, NVM and power-sequence checklist
A joint engineering/procurement checklist for exact PMIC orderables, default voltages, phases, startup sequence and fault behavior. Same family or package does not establish identical NVM, and suffixes are not a configuration decoder.
Read guide and checklist →Automotive protection switches: load limits, reverse blocking and energy budgets
Separate TPS1HB16/TPS2HB16 smart high-side switches from the LM7480 external-MOSFET controller, reviewing A/B/F current limits, reverse paths, hot losses, inrush and recovery.
Read guide and checklist →High-side switch thermal and line-fuse coordination: from thermal feedback to fault clearing
Coordinate hot RON, board-level thermal resistance, transient thermal impedance, dual-channel coupling and harness/fuse time-current uncertainty for TPS1HB16-Q1, TPS2HB16-Q1 and LM7480-Q1, with an explicitly assumed calculation and a reversible bench checklist.
Read guide and checklist →Vehicle communication and interfaces
Distinguish controller and physical layer, wake and power, and Ethernet versus camera-link boundaries.
CAN FD controller, transceiver or SBC: select the missing function
Compare the roles of TCAN1042, TCAN1044A, TCAN1043A, TCAN1145, TCAN1167, TCAN4550 and ISO1042, separating SPI access, selective wake, power and isolation.
Read guide and checklist →LIN or CAN FD: start with message deadlines, harness and sleep policy
Use TLIN1029-Q1 and TI CAN candidates to plan body subnets, separating 20 kbps LIN transmission, 100 kbps programming reception, controller roles and gateway acceptance.
Read guide and checklist →Automotive Ethernet and FPD-Link: distinguish network endpoints from camera links
Compare DP83TC811, DP83TC812S and DP83TG720S with DS90UB953/954/960, covering MAC interfaces, explicit pairing, camera aggregation and usable-bandwidth budgets.
Read guide and checklist →FPD-Link camera bandwidth: from input lanes to line deadlines and DMA
Use the actual DS90UB935/936/962/913A interfaces and a DS90UB960 line-level example to check CSI-2 lanes, forwarding, virtual channels, blanking and memory traffic instead of approving a design from average pixel rate.
Read guide and checklist →FPD-Link camera diagnostics: from LOCK to per-stream isolation and recovery
Use a DS90UB953-Q1 → DS90UB960-Q1 example to separate power, clock, PoC, harness, serial-link, CSI and SoC VC/DMA faults with evidence-first snapshots, staged tests and bounded recovery.
