Introduction

AI Translation

The TPS3840-Q1 series voltage monitor/reset IC operates at high voltage levels while maintaining very low quiescent current across the full VDD and temperature range. The TPS3840-Q1 delivers an optimal combination of low power consumption, high accuracy, and low propagation delay (tp_HL = 30μs typical). The reset output signal is asserted when the voltage on VDD falls below the negative voltage threshold (VIT-) or when manual reset is pulled to logic low (VMR_). The reset signal is deasserted when VDD rises above VIT- plus hysteresis (VIT+), the manual reset (MR̄) is floating or above VMR_H, and the reset delay time (tD) has expired. The reset delay time can be programmed by connecting a capacitor between the CT pin and ground. For fast reset, the CT pin can be left floating. Additional features include: low power-on reset voltage (VPOR), built-in glitch suppression protection for MR̄ and VDD, built-in hysteresis, and low open-drain output leakage current (ILKG(OD)). The TPS3840-Q1 is an ideal voltage monitoring solution for automotive applications and battery-powered/low-power applications.
