Mouser Electronics, Inc., the New Product Introduction (NPI) leader empowering innovation, is now stocking the TPS3840 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-power, industrial, 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.
