ZSSC5101BE4R

Overview

The ZSSC5101BE4R is a CMOS integrated circuit designed as a sensor signal conditioner for magnetoresistive bridge sensors. It converts sine and cosine signals from AMR, GMR, or TMR bridges into a ratiometric analog voltage output with up to 4608 analog steps and a step size as small as 0.022°. The device supports programmable linear transfer characteristics, including zero position, angular range, and clamping levels, via a one-wire interface through the output pin. It features offset and amplitude calibration, broken-wire diagnostics, and loss of magnet indication. Automotive-qualified to AEC-Q100 Grade 0, it operates in ambient temperatures up to 150°C in SSOP-14 packages.

Feature Summary

• Accepts anisotropic, giant, and tunnel magnetoresistive bridge sensors (AMR, GMR, and TMR) for both rotational and linear movement applications.
• Enables in-line programming of fully assembled 3-wire sensors through the output pin using a one-wire interface.
• Includes programmable 32-bit user ID, CRC error detection, and error correction on EEPROM data.
• Provides diagnostic capabilities such as broken-wire detection and loss of magnet indication with programmable threshold levels.

Applications

• Automotive steering angle sensing
• Linear position detection systems
• Rotational position monitoring
