TLV365-Q1

The TLV365-Q1 is a high-speed, low-power comparator from Texas Instruments designed for automotive and industrial applications. It operates over a wide supply voltage range of 2.7 V to 5.5 V, making it suitable for both 3.3 V and 5 V systems. The device features a propagation delay as low as 100 ns, enabling fast response times critical in real-time control systems. With a typical supply current of only 80 µA, the TLV365-Q1 delivers excellent power efficiency, ideal for battery-powered or energy-sensitive designs. This comparator includes an open-drain output stage that supports push-pull or open-collector configurations, offering flexibility in interfacing with various logic families and microcontrollers. Its input common-mode range extends from ground to the supply voltage, allowing direct signal comparison without requiring external level-shifting circuitry. The internal hysteresis (typically 1 mV) enhances noise immunity, ensuring stable switching even in electrically noisy environments. The TLV365-Q1 is qualified to AEC-Q100 Grade 1 standards, guaranteeing reliability under harsh automotive conditions such as extreme temperatures (-40°C to +125°C), vibration, and EMI. This makes it well-suited for use in engine control units (ECUs), battery management systems (BMS), motor control, and sensor interface circuits within vehicles. Additionally, its robust design ensures long-term operational stability in industrial automation, medical equipment, and consumer electronics where precision and durability are essential. In terms of functionality, the TLV365-Q1 provides a simple yet powerful solution for threshold detection, window detection, and analog-to-digital conversion tasks. It can be configured as a single-ended or differential comparator depending on the application needs. The device also supports rail-to-rail input and output operation, maximizing dynamic range and minimizing signal loss. With no external components required for basic operation, it reduces board space and simplifies design while maintaining high performance. Overall, the TLV365-Q1 combines speed, low power consumption, automotive-grade reliability, and ease of integration—making it a versatile choice for engineers seeking a dependable comparator in demanding environments.
