Shenzhen Meiyuxin Technology Co., Ltd. supplies TLV840MADL32DBVRQ1 auto low voltage monitor with reset delay time and manual reset! ! 

Product Description:

The TLV840-Q1 device is a voltage supervisor or reset IC that can operate at wide input voltage levels from 0.7 V to 6 V while maintaining very low quiescent current across the whole VDD and temperature range. TLV840-Q1 offers the best combination of low power consumption, high accuracy and low propagation delay (tp_HL= 30 µs typical).

Reset output signal is asserted when the voltage at VDD drops below the negative voltage threshold (VIT-). Reset signal is cleared when VDD rise above VIT- plus hysteresis (VHYS) and the reset time delay (tD) expires. Reset time delay can be programmed by connecting a capacitor between the CT pin and ground. For a minimum reset delay time the CT pin can be left floating. The TLV840-Q1, with its manual reset pin (MR), offers program flexibility by forcing the system into a hard reset when the pin is asserted.

Additional features: Low power-on reset voltage (VPOR), built-in glitch immunity protection for VDD, built-in hysteresis, low open-drain output leakage current (Ilkg(OD)). TLV840-Q1 is a perfect voltage monitoring solution for automotive applications and battery-powered / low-power applications.
