A1162

Programmable Precision Hall-Effect

Switch with Advanced Diagnostics

FEATURES AND BENEFITS

DESCRIPTION

• User-programmable unipolar switchpoints

The A1162 is a unipolar Hall-effect switch with an externally

• Integrated diagnostics for enhanced system safety and

reliability

enabled diagnostic function and user-programmable

switchpoints. On-chip electromagnetic coils are used to

implementself-testofthesensor’sentiremagneticandelectrical

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.

□ Enabled on demand

□ Integrated electromagnetic coils test the entire sensor

signal path

□ Designed for ISO 26262/ASIL systems (QM)

• Chopper stabilized

□ Resistant to physical stress

□ Superior temperature stability

• Internal regulator for wide operating voltage range

□ 3.8 to 24 V

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 (>B_OPmax). The output transistor of theA1162

switches off (output signal switches high) when the magnetic

field is removed (<B_RPmin).

• Automotive-grade ruggedness

□ Solid-state reliability

□ Reverse-battery protection

□ Output short-circuit protection

□ AEC-Q100 qualified

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.).

• Small surface-mount package

PACKAGE:

8-Pin eTSSOP (Suffix LE)

This monolithic IC integrates a voltage regulator, Hall voltage

generator,small-signalamplifier,chopperstabilization,Schmitt

trigger, and short-circuit-protected open-collector output able

to sink up to 25 mA. The on-board regulator permits operation
