Automotive angle sensor with PWM output
The TLE5014P16XUMA1 from Infineon is an automotive-qualified (AEC-Q100) angle sensor covering 0° to 360° electrical and mechanical rotation. It outputs a PWM signal proportional to the angle, which connects directly to a standard MCU timer input without an ADC. The sensor measures angle, linear position, and rotary position using an external magnet (not included). The sine/cosine output signals from the Hall plates are processed internally to produce the PWM duty cycle. Supply voltage is 4.2 V — not a standard 3.3 V or 5 V rail, so a small LDO or regulator is needed to drop from 5 V. The operating temperature range of -40°C to 125°C covers under-hood and chassis-mount automotive environments.
PWM interface and supply rail planning
The PWM output eliminates the need for an SPI or SENT bus, reducing pin count on the controller. The duty cycle encodes the absolute angle over the full 360° range, with resolution set by the PWM carrier frequency. Because the supply is 4.2 V, the designer must add a regulator if the system rail is 5 V or 3.3 V. A 100 nF decoupling cap at the sensor pin is standard; the regulator's output noise should stay below 50 mVpp to avoid jitter on the PWM edge.
Active production and sourcing
Infineon lists no successor or cross-reference — this is the current-generation part for the TLE5014 series. It ships in Tape & Reel (TR) and Cut Tape (CT) options, surface-mount PG-DSO package with gull-wing leads. Sourced per RFQ against the BOM quantity; no stock-holding claim.
