CS8190ENF16

Specialized ICS Overview

The CS8190ENF16 is a precision air-core tachometer and speedometer driver manufactured by onsemi. Designed for automotive applications, it accepts a speed sensor input and generates sine and cosine related output signals to differentially drive an air-core meter movement. The device integrates a high-impedance input comparator, charge pump, voltage regulator, and function generator. It operates within a supply voltage range of 8.5 V to 16 V and withstands 60 V transients. Key features include return-to-zero functionality, low pointer flutter, and internally fused leads in the PDIP-16 package.

Specialized ICS Feature Summary

• Differential Sine/Cosine Drivers: Eliminates the need for external zener references and provides higher torque for analog meter movements.
• High Transient Protection: Withstands 60 V transients, reducing the requirement for external protection circuitry.
• Return to Zero: Ensures the meter needle returns to the zero position upon power-down or undervoltage conditions.
• Internally Fused Leads: The PDIP-16 package includes internal fusing for enhanced reliability.

Specialized ICS Applications

• Automotive Speedometers
• Automotive Tachometers
• Air-Core Meter Movements

Specialized ICS Procurement Notes

Verify the specific ordering suffix 'NF' corresponds to the PDIP-16 package when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for any discontinuation notices or recommended replacement parts from onsemi before finalizing procurement plans.

Specialized ICS Selection Notes

Select this component for designs requiring direct interfacing with air-core meters without external differential amplifiers. Ensure the application environment supports the specified operating temperature range of -40°C to +105°C. Verify that the input signal frequency falls within the 0 to 20 kHz range for optimal performance.

Specialized ICS Part Context

The CS8190 series serves as an upgrade over industry-standard drivers like the CS289 or LM1819. The ENF16 variant specifically denotes the PDIP-16 through-hole package option. This part is part of onsemi's specialized IC lineup for automotive instrumentation, focusing on precision and robustness in harsh electrical environments.

Specialized ICS Replacement Considerations

Consult onsemi technical support for current availability and potential obsolescence status. If the PDIP-16 package is unavailable, consider the SO-20W variant (CS8190EDWF20G) if board layout permits, noting the pinout differences and thermal characteristics.
