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.
