ZSSC5101BE4T

Overview

The ZSSC5101BE4T is a CMOS integrated circuit designed as an xMR sensor signal conditioner. It converts sine and cosine signals from magnetoresistive bridge sensors (AMR, GMR, TMR) into a ratiometric analog voltage output with up to 4608 analog steps and a step size as small as 0.022°. The device supports user-programmable linear transfer characteristics, including zero position, angular range, and clamping levels. It features in-line programming via the output pin using a one-wire interface, storing parameters in EEPROM. Automotive-qualified to AEC-Q100 Grade 0, it operates within an ambient temperature range of -40°C to +150°C for the SSOP-14 package.

Feature Summary

• Accepts anisotropic, giant, and tunnel magnetoresistive bridge sensors for rotational or linear movement applications
• Enables in-line programming through the output pin via a one-wire interface without requiring dedicated test pins
• Provides diagnostics including broken-wire detection and loss of magnet indication with programmable thresholds
• Includes error detection and correction capabilities on EEPROM data with a programmable 32-bit user ID CRC

Applications

• Automotive steering angle sensing systems
• Linear position sensing in automotive actuators
• Rotational position monitoring in industrial control systems

Procurement Notes

Verify the specific suffix BE4T against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm current lifecycle status, as previous listings indicate potential obsolescence for related variants. Ensure compatibility with existing sensor bridge configurations before procurement.

Selection Notes

Select this component when utilizing AMR, GMR, or TMR sensors requiring high-resolution analog output. It is suitable for designs needing programmable travel ranges and clamping levels. Verify that the application environment stays within the specified temperature limits for the chosen package variant.

Part Context

The ZSSC5101 belongs to Renesas' xMR Sensor Signal Conditioner family. It serves as an Analog Front End (AFE) specifically tailored for magnetoresistive sensors. This series focuses on providing calibrated, linear outputs directly from raw sensor signals, simplifying system design for position sensing applications.

Replacement Considerations

Check for direct cross-reference part numbers in Renesas catalogs. Previous data indicates the ZSSC5101BE1B wafer variant may be obsolete; verify if BE4T shares similar lifecycle constraints. No alternative part numbers are confirmed in the provided source material.
