Mouser Electronics Now Stocking Texas Instruments TPS3840 Super-Efficient Nanopower Voltage Supervisors

August 28, 2019 – Mouser Electronics, Inc., the New Product Introduction (NPI) leader empowering innovation, is now stocking theTPS3840 family of nanopower high-input voltage supervisors from Texas Instruments (TI). The TPS3840 devices are reset ICs that can operate at up to 10 V while maintaining very low quiescent current across all operating conditions. The devices provide a combination of minimal power consumption, high accuracy, and low propagation delay to help extend battery life for a variety of low-powerindustrial, and battery-powered applications.

TI’s TPS3840 voltage supervisors, available from Mouser Electronics, deliver a broad input voltage of 1.5 V to 10 V, which enables the monitoring of 9 V rails or batteries with no external components as well as 24 V rails with external resistors. The devices’ nano-quiescent current (nano-Iq) of 350 nA (typical) increases battery life for low-power applications and reduces current consumption when utilizing those external resistors. With less than a 1 µA current consumption, the ICs can be configured to work as either a comparator (with a simple three-pin configuration) or as a daisy-chained universal power supply supervisor that acts as a sequencer.

The devices’ fast start-up delay allows the detection of a voltage fault before the rest of the system powers up, providing maximum safety in hazardous start-up fault conditions, and the low power-on-reset (VPOR) prevents false resets, premature enable or turn-on of next device, and proper transistor control during power-up and power-down. Additional features include a 1-percent typical monitor threshold accuracy, built-in glitch immunity protection for manual reset and VDD, built-in hysteresis, and low open-drain output leakage current.

The TPS3840 voltage supervisors are available in a five-pin, industry-standard SOT-23 package, with three output topology options: open-drain, active-low (TPS3840DL); push-pull, active-low (TPS3840PL); and push-pull, active-high (TPS3840PH). Target power management applications include grid infrastructure equipment, such as circuit breakers, smart meters, and other monitoring and protection equipment; factory and building automation; electronic point of sale devices; and portable and battery-powered systems.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
