3 Description

The TPS3840-Q1 family of voltage supervisors or

reset ICs can operate at high voltage levels while

maintaining very low quiescent current across the

whole VDD and temperature range. TPS3840-Q1

offers 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-)

or when manual reset is pulled to a low logic (VMR_L).

Reset signal is cleared when VDD rise above VIT- plus

hysteresis (VIT+) and manual reset (MR) is floating or

above VMR_H and the reset time delay (tD) expires.

Reset time delay can be programmed by connecting

a capacitor between CT pin and ground. For a fast

reset CT pin can be left floating.

Additional features: Low power-on reset voltage

(VPOR), built-in glitch immunity protection for MR and

VDD, built-in hysteresis, low open-drain output

leakage current (ILKG(OD)). TPS3840-Q1 is a perfect

voltage monitoring solution for automotive

applications and battery-powered / low power

applications.
