The TLV40x1 devices are low-power, high-accuracy comparators with precision references and fast response. The comparators are available in an ultra-small, DSBGA package measuring 0.73 mm × 0.73 mm, making the TLV40x1 applicable for space-critical designs like portable or battery-powered electronics where low-power and fast response to changes in operating conditions is required.

The factory-trimmed references and precision hysteresis combine to make the TLV40x1 appropriate for voltage and current monitoring in harsh, noisy environments where slow moving input signals must be converted into clean digital outputs. Similarly, brief glitches on the input are rejected ensuring stable output operation without false triggering.

The TLV40x1 are available in multiple configurations allowing system designers to achieve their desired output response. For example, the TLV4021 and TLV4041 offer a non-inverting input, while the TLV4031 and TLV4051 have an inverting input. Furthermore, the TLV4021 and TLV4031 feature an open-drain output stage, while the TLV4041 and TLV4051 feature a push-pull output stage. Lastly, each comparator in the TLV40x1 family is available with a 0.2V, 0.5V, or 1.2V precision reference.

CIRCUIT060037 — 精密過電流閂鎖電路

這個高壓側電流感測解決方案採用電流感測放大器、含整合式參考的比較器以及 P 通道 MOSFET，以建立過電流閂鎖電路。當偵測到負載電流大於 200 mA 時，電路會中斷系統與電源的連接。比較器輸出將閂鎖 (將 P 通道 MOSFET 的閘極電壓保持在 0 V)，直到電路的電源開始循環，因為比較器會驅動 P 通道 MOSFET 的閘極，並將訊號傳送回電流感測放大器的參考針腳。

CIRCUIT060083 — 具有比較器電路的欠電壓保護

This undervoltage, protection circuit uses one comparator with a precision, integrated reference to create an alert signal at the comparator output (OUT) if the battery voltage sags below 2.0 V. The undervoltage alert in this implementation is ACTIVE LOW. So when the battery voltage drops below (...)
