PMIC - Supervisors: TPS3808G12DRVR Application Field and Working Principle

The TPS3808G12DRVR is a supervisor integrated circuit (IC) designed for use in Power Management and Control applications. Its primary function is to monitor battery levels and supply over-voltage and under-voltage protection. This supervisor IC can detect input voltage in two ranges, one from 2.6 V to 4.1 V and the other from 4.3 V to 6.0 V.The TPS3808G12DRVR is widely used in mobile devices such as tablets, mobile phones, and notebook computers, as well as in automotive, communications, industrial, and consumer applications. It is also used in power applications such as power converters, industrial chargers, motor control systems, and portable devices.The TPS3808G12DRVR supervisor is an ultra-low power, low voltage SMD IC with an operating temperature range of -40°C to +85°C. It is a one-time programmable (OTP) low voltage supervisor IC with a single-supply operating voltage range of 1.62V to 6.0V. The supervisor has an on-chip voltage detection circuit, voltage monitoring circuit, and voltage reset circuit that detects, monitors, and resets the system, respectively.The TPS3808G12DRVR features a Selectable Reset pin (SR) that can be programmed as a digital input pin or a reset output pin. This supervisor IC also features an adjustable reset timeout period (max≤15s), an adjustable reset threshold voltage (Vths1 and Vths2), an adjustable reset-timeout leakage current, and a longer reset timeout period.The TPS3808G12DRVR’s low-power operation ensures that the supervisor does not interfere with other system components. Its wide operating voltage range and extended temperature range enable the use of this IC in a variety of applications. The ultra-low power operation of the TPS3808G12DRVR also ensures that there is no power loss in the system during standby or no-load conditions.The TPS3808G12DRVR is easy to use, with no additional external components required. This supervisor IC is available in various packages, including the TSSOP-8L and WLCSP-8L packages. With its wide operating voltage range, wide voltage monitoring range, low-power operation, and extended temperature range, the TPS3808G12DRVR supervisor can help enhance the reliability and performance of various applications.
