Product Overview: TLV840NADL46DBVR from Texas Instruments
The TLV840NADL46DBVR is a high-performance, low-power voltage supervisor designed and manufactured by the reputable Texas Instruments. This device is specifically engineered to monitor and maintain the stability of system voltages, ensuring that electronic products operate within their specified voltage ranges. It is an essential component for a wide range of applications, including portable electronics, microcontrollers, and systems that require precise voltage supervision.
The TLV840NADL46DBVR features a fixed-sense threshold voltage of 4.6V, which makes it ideal for supervising 5V power supplies. Its low supply current of only 350 nA (typical) makes it an energy-efficient choice for battery-operated devices. Moreover, the device offers a ±1% threshold accuracy over the entire temperature range of -40°C to +125°C, ensuring reliable performance under various environmental conditions.
This voltage supervisor comes in a compact SOT-23-5 package, allowing for easy integration into space-constrained designs. Its small footprint makes it suitable for portable devices where board space is at a premium. The TLV840NADL46DBVR also features a built-in delay circuit that provides a programmable time delay, which helps prevent false triggering due to transient voltages and ensures that the system has stabilized before enabling the power-good output.
The device's open-drain, active-low RESET output remains asserted until the monitored voltage reaches the reset threshold and the delay time has elapsed, providing a robust power-on reset functionality. The output is capable of sinking significant current, which makes it compatible with most microcontrollers and other digital systems.
Texas Instruments has designed the TLV840NADL46DBVR with industry-standard features and reliability, making it a versatile choice for designers who require a dependable voltage supervision solution. Its combination of precision, low power consumption, and small package size ensures that it meets the stringent requirements of modern electronic systems.
