Overview

The TLV3691IDPFR is an ultra-low power single-channel comparator designed for power-sensitive applications, operating on a supply voltage as low as 0.9V. It features a rail-to-rail input stage and a push-pull output, consuming a maximum quiescent current of only 150nA. This nanopower performance makes it ideal for monitoring tasks in systems where every nanoampere of battery life is critical.

Why Choose This Part

The primary advantage is the 150nA maximum quiescent current combined with a wide operating temperature range of -40 to 125 degrees Celsius. Its tiny 1mm x 1mm X2SON package saves significant board space, while the 0.9V minimum supply voltage allows it to operate directly from single-cell alkaline or silver-oxide batteries. Internal hysteresis and a 100pA maximum input bias current simplify design for high-impedance signal sources.

Applications

Battery Voltage Monitoring
Providing low-battery detection in portable electronics with minimal impact on battery life.
Energy Harvesting Systems
Managing power-up sequences in systems scavenging energy from solar, thermal, or vibration sources.
Window Comparators
Implementing threshold detection in ultra-low power industrial sensors and remote nodes.
Zero-Crossing Detectors
Low-frequency signal processing in battery-powered instrumentation.

Getting Started

Designers should prioritize decoupling with a 0.1uF capacitor close to the VDD pin to ensure stability despite the low power consumption. When prototyping, use a 0.5mm pitch breakout board or a dedicated evaluation module like the TLV3691EVM for performance verification. Pay close attention to PCB leakage currents, which can easily exceed the device's own 150nA supply current if the board is not clean or properly guarded.
