TLV4314QPWRQ1 Automotive-Grade Quad Precision Shunt Voltage Reference with AEC-Q100 Grade 1 and Low Power Consumption

1. Core Functions

1. 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.
2. 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.
3. 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.
4. 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.
