DS1238S+T&R

PMIC – Supervisors are a type of integrated circuit (IC) used in electronic systems. These ICs act as an interface between the logic and power system. PMICs – Supervisors typically provide voltage and temperature monitoring, system reset, over-voltage and under-voltage protection, and power-on reset. The DS1238S+T&R is one such PMIC – Supervisors integrated circuit.

The DS1238S+T&R provides protection and performance monitoring for systems requiring a single +5V power supply. It includes several features such as a brown-out reset (BOR), temperature-compensated reset, temperature-limited reset, and power-on reset. The IC can be programmed to monitor power supply voltages with a resolution of up to 50 mV, and can detect and report malfunctions in the power supply. The IC can also detect reset events that occur due to a variety of conditions, including over-voltage, under-voltage, excessive temperature, and loss of power. In addition, the IC has integrated error protection and reporting, which prevents incorrect operation of the system due to a variety of events, such as power interruptions or shorts.

The DS1238S+T&R is designed to operate in a variety of applications. It is suitable for monitoring supplies up to 25 V, and can detect and protect in a variety of operating ranges. Its integrated reset signal is available on an open-drain output pin and it is compatible with most platforms, including microcontrollers and Field Programmable Gate Arrays (FPGA). Additionally, its open-drain output can be connected to a logic signal for additional programming.

The DS1238S+T&R contains an internal reset generator and latch that monitors the voltage and temperature levels. When the voltage level is below the BOR threshold or the temperature level is out of range, an active reset is immediately issued. The reset signal is asserted for a predetermined period of time, or until the power supply reaches the appropriate levels. During reset operations, the reset output is driven low and the device is placed in a low-power state.

The DS1238S+T&R also contains an over-voltage and under-voltage detection circuit, which can be used to monitor the sense supply. The over-voltage detector compares the sense supply voltage to an internally programmable voltage reference. If the voltage exceeds the over-voltage threshold, the device will issue a reset, and then shut down the system.

The DS1238S+T&R is a versatile solution for power monitoring and protection applications. It provides high reliability and performance, and is suitable for use in a wide range of systems. By monitoring the power supply, the device can protect the system from over-voltage and under-voltage conditions, and can detect and reset the system in response to temperature and voltage events. The device also includes integrated protection and reporting circuitry to ensure safe operation of the system.
