Product Description

The TPS3852 voltage supervisor is a high-reliability H18 reset IC designed for automotive applications, offering robust voltage monitoring in harsh environments. This QDRBRQ1 automotive-grade device monitors a single voltage rail (1.8V nominal) with an adjustable threshold range (1.6V to 5.5V) and generates a reset signal when the input voltage falls below the preset level. It operates within a wide supply range (1.2V to 6.5V) and withstands temperatures from -40°C to +125°C, ensuring compliance with automotive standards. Featuring a manual reset input and a fixed delay time (typ. 200ms), it directly interfaces with microcontrollers or power management modules without external components. Key advantages include ultra-low quiescent current (5µA) for battery-sensitive systems, high noise immunity, and AEC-Q100 qualification. The compact 8-pin SON package suits space-constrained automotive systems like ADAS, ECUs, and infotainment, though lacks multi-channel monitoring or programmable delay flexibility.
