TLE4929C Crankshaft Sensor

Fully Programmable Crankshaft Sensor

Applications

The TLE4929C is an active Hall sensor ideally suited for crankshaft

applications and similar industrial applications, such as speedometer or

any speed-sensor with high accuracy and low jitter capabilities.

Features

• Measures speed and position of tooth/pole wheels

• Switching point in middle of the tooth enables backward compatibility

• Magnetic stray-field robustness due to differential sensing principle

• Digital output signal with programmable output-protocol including

diagnosis interface

• Direction detection and Stop-Start-Algorithm

• High accuracy and low jitter

• High sensitivity enable large air gap

• End-of-line programmable to adapt to engine parameters

• Can be used as a differential Camshaft sensor

• Wide automotive operating temperature range

Typical Application Circuit

Description

The TLE4929C comes in a RoHs compliant three-pin

package, qualified for automotive usage. It has two

integrated capacitors on the lead frame (Figure 1). These capacitors increase the EMC resistivity of the device.

A pull-up resistor RLoad is mandatory on the output pin and determines the maximum current through the

output transistor.
