FAQ
What output protocols does the MLX90372GVS-ACC-308-RX support?
The MLX90372GVS-ACC-308-RX supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via programming. In SENT mode, it transmits 12-bit position data with CRC-protected diagnostics in a secure sensor frame format. PWM mode delivers position as duty cycle (0–100%) with configurable frequency and resolution. The ACC-308 variant defaults to SENT 3 µs tick time in DMP-4 Pinout-A configuration.
Is the MLX90372GVS-ACC-308-RX pin-compatible with other MLX90372 variants in DMP-4 packaging?
Yes - the MLX90372GVS-ACC-308-RX uses DMP-4 Pinout-A (VSS–VDD–OUT–VSS), matching all other MLX90372GVS variants with Pinout-A (e.g., ACE-308, ADE-308). Pinout-B variants (e.g., ACC-301) differ by relocating OUT to Pin 1 and adding an INPUT pin at Pin 4, so physical interchangeability requires verification of pin assignment and application circuit compatibility.
Does the MLX90372GVS-ACC-308-RX require external decoupling capacitors?
No - the MLX90372GVS-ACC-308-RX in DMP-4 packaging includes built-in decoupling capacitors per section 15.3 of the datasheet. This eliminates the need for external 100 nF ceramic capacitors typically required on VDD/VDEC pins in SOIC-8 or TSSOP-16 versions, reducing component count and PCB area in compact sensor modules.
What is the functional safety status of the MLX90372GVS-ACC-308-RX?
The MLX90372GVS-ACC-308-RX is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC), with documented safety mechanisms including CRC-protected SENT frames, dual watchdog timers (IWD/AWD), memory ECC, and diagnostic cycle timing checks. It is AEC-Q100 qualified for Grade 0 (-40°C to +160°C), enabling integration into ASIL-B or ASIL-C automotive systems when used per the safety manual.
Can the MLX90372GVS-ACC-308-RX be reprogrammed in-system?
Yes - the MLX90372GVS-ACC-308-RX supports end-user programming via SENT interface using Melexis' PTC (Programmer Tool Chain) software. Users can configure output mode (SENT/PWM), transfer characteristic (4/8/16/32-point PWL), measurement range, diagnostics thresholds, and identification data (48-bit ID). Reprogramming requires no dedicated hardware programmer - only a SENT-capable host controller and appropriate firmware.
