TLV840MADL30DBVRQ1

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 (V_IT-). Reset signal is cleared when VDD rise above V_IT- plus hysteresis (V_HYS) 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 (V_POR), built-in glitch immunity protection for VDD, built-in hysteresis, low open-drain output leakage current (I_IKg(OD)). TLV840-Q1 is a perfect voltage monitoring solution for automotive applications and battery-powered / low-power applications.
