DESCRIPTION
The A1162 is a unipolar Hall-effect switch with an externally
enabled diagnostic function and user-programmable
switchpoints. On-chip electromagnetic coils are used to
implement self-test of the sensor’s entire magnetic and electrical
signal chain. It is designed for systems where precise magnet
switchpoints and safety, reliability, or both, are critical, such
as those designed to meet the requirements of ISO 26262.
In normal operating mode, the A1162 functions as a standard
unipolar Hall-effect switch. The device output transistor turns
on (output signal switches low) in the presence of sufficient
magnetic field (>BOP max). The output transistor of the A1162
switches off (output signal switches high) when the magnetic
field is removed (<BRP min).
When the diagnostic feature is enabled, the output of theA1162
provides a square wave output which confirms the device
is properly sensing the internally generated magnetic field.
Therefore, use of the A1162 either eliminates the need for
redundant sensors in safety-critical applications or increases
robustness in safety-critical applications that might otherwise
require redundant sensors (drive-by-wire systems, etc.).
This monolithic IC integrates a voltage regulator, Hall voltage
generator, small-signal amplifier, chopper stabilization, Schmitt
trigger, and short-circuit-protected open-collector output able
to sink up to 25 mA. The on-board regulator permits operation
