The TL4050-Q1 family of shunt voltage references are versatile easy-to-use references designed for a wide array of applications. The two-terminal fixed-output device requires no external capacitors for operation and is stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low temperature coefficient to maintain a stable output voltage over a wide range of operating currents and temperatures.

The TL4050-Q1 is available in three initial tolerances, ranging from 0.1% (maximum) for the A grade to 0.5% (maximum) for the C grade. Thus, a great deal of flexibility is available to designers in choosing the best cost-to-performance ratio for an application. Packaged in the space-saving SOT-23-3 and SC-70 packages and requiring a minimum current of 45µA (typical), the TL4050-Q1 also is designed for portable applications.

The TL4050x-Q1 characterization is for operation over an ambient temperature range of –40°C to 125°C.

参考设计

TIDA-01513 — 汽车高压和隔离泄漏测量参考设计

此参考设计的功能是监控高压总线到机箱接地的隔离电阻。由于电池管理系统、牵引逆变器、直流/直流转换器、车载充电器和其他子系统在高电压（大于 60V）下运行，监控耦合器件和从高电压到机箱接地组件的隔离能力是 HEV 和 EV 的必备功能。
