Introduction
TLV4314QPWRQ1 - Quad Precision Shunt Voltage Reference
The TLV4314QPWRQ1 is a quad, precision shunt voltage reference optimized for automotive applications, compliant with AEC-Q100 Grade 1 standards.
Core Functions
Precision Voltage Referencing
Provides four independent, stable reference voltages (adjustable via external resistors, or fixed at target values) with a typical initial accuracy of ±0.4% over the full temperature range.
Shunt Regulation Operation
Works in shunt mode: when the anode-cathode voltage exceeds the reference threshold, the device conducts current to clamp the output voltage at a stable level, enabling voltage stabilization for loads or sensing circuits.
Low Power Consumption
Operates with a low minimum cathode current (as low as 100 μA), minimizing power draw in battery-powered or low-power automotive systems.
Automotive-Grade Robustness
Withstands extended temperature ranges (-40°C to +125°C) and meets AEC-Q100 reliability requirements, including ESD protection (up to 4 kV HBM) and overcurrent tolerance.
Typical Applications
Automotive Electronics Systems
- Engine control units (ECUs) for sensor signal conditioning and ADC reference
- Battery management systems (BMS) for voltage monitoring of Li-ion/pack batteries
- Infotainment and lighting systems for stable voltage supply to precision components
Industrial Control & Instrumentation
- Precision analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) reference voltage
- Process control sensors (temperature, pressure, flow) for signal calibration
- Power supply voltage monitoring and overvoltage protection circuits
Consumer & Communication Devices
- Portable medical devices requiring stable reference voltages
- Telecom infrastructure equipment for line card voltage regulation
