Product Description

The APS12450 is a three-wire planar Hall-effect sensor IC designed for automotive safety-related systems, developed in accordance with ISO 26262:2011 with ASIL B capability. It features an enhanced three-wire interface with interconnect open/short diagnostics and a fault state for diagnostic communication, maintaining compatibility with legacy systems. Continuous background diagnostics are transparent to the host, reducing fault tolerant time. Product options include magnetic switchpoints, temperature coefficient, and output polarity, with response adaptable to SmCo, NdFeB, or ferrite magnets. For a functionally equivalent three-wire switch device, refer to the APS11450.

Key Features and Benefits

Functional safety developed to ISO 26262:2011 (ASIL B pending assessment)
Integrated background diagnostics for signal path, regulator, Hall plate and bias, overtemperature detection, and nonvolatile memory
Defined fault state
Multiple product options for magnetic polarity, switchpoints, hysteresis, temperature coefficient, and output polarity
Reduces module Bill-of-Materials (BOM) and assembly cost through ASIL B sensor replacing redundant sensors and integrated overvoltage clamp and reverse-battery diode
Automotive-grade ruggedness and fault tolerance with extended AEC-Q100 Grade 0 qualification (operation to 175C junction temperature)
3 to 30 V operating voltage range
8 kV HBM ESD protection
Overtemperature indication
Monolithic ICs with on-chip reverse-battery protection, overvoltage protection (40 V load dump), ESD protection, overtemperature detection, and internal voltage regulator
Available in industry-standard SOT (LH) and SIP (UA) packages, RoHS-compliant and lead (Pb) free

Typical Applications

Automotive and industrial safety systems
Seat/window motors
Sun roof/convertible top/tailgate/liftgate actuation
Brake and clutch by wire actuators
Engine management actuators
Electric power steering (EPS)
Transmission shift actuator
