Plan INA290 unidirectional current sensing by checking the gain suffix, shunt polarity, common-mode range, output headroom and ADC acquisition chain.

Bring up a TMP144 sensor chain with explicit SMAART Wire initialization, assigned device IDs, signed temperature decoding and complete response checks.

Plan TPS22919 switching with deliberate ON control, realistic current ratings, fixed slew behavior, output discharge and protected-load qualification.

Check ADS8326 clock-dependent acquisition, near-ground negative input, reference range and straight-binary framing before interpreting sample voltage.

Plan ADS8866 sampling with explicit CONVST and DIN behavior, near-ground negative input limits, reference drive and unsigned 16-bit decoding.

Use TCA9535 GPIO safely by defining external input bias, preloading output latches, mapping both ports and servicing the correct interrupt source.

Plan TPS65133 fixed plus and minus 5 V rails with the correct converter topology, shared enable, sequenced startup, loading and discharge behavior.

Check TPS63020 output demand, dynamic current limits, power-save selection and its current-loop power-good indication across the battery voltage range.

Configure DRV8889-Q1 stepping, winding current, decay mode and stall learning deliberately before using a diagnostic flag to infer mechanical motion.

Plan a TPS2663 protected power path by checking the exact variant, external reverse-blocking FET, power limit, startup demand and recovery policy.
