Programmable linear Hall-effect sensor IC - MLX90292
Product description
The MLX90292 is a SMD redundant programmable linear Hall sensor IC with digital reporting protocol for position sensor applications with high safety requirements (ISO 26262 - ASIL) and/or small data latency.
The MLX90292 is available in TSSOP-16 package featuring two independent and isolated dies for redundancy purpose.
The measured magnetic flux density is conditioned through a fast DSP and reported through 2-wire PAS-4, 2-wire PSI5 (asynchronous mode - point-to-point), 2-/3-wire PWM. Latency time is less than 500 us.
All magnetic response functions of the MLX90292 are fully programmable for versatility and system tolerances reduction (end-of-line calibration).
The output quiescent data (i.e. Data @ B = 0 Gauss), sensitivity, sensing polarity, the magnitude of sensitivity drift over temperature (TC - 1st & 2nd order), the transfer characteristic linearity (piecewise linearization), the thermal Voq drift and the signal bandwidth, are all programmable through the 2-wire connector terminals (Vdd-Vss).
The MLX90292 has a very stable thermal compensation for both the sensitivity and the output quiescent data over a broad temperature range.
It features active error correction circuitry (quadrature spinning current and chopper stabilized amplifier), which virtually eliminates the offset errors normally associated with Hall-effect devices.
