The DS1233-15/T&R is a low voltage supervisory circuit designed to monitor supply voltages and limit inrush current while keeping manual reset pins active during system power-up. It is a small, easy-to-use device, making it ideal for applications such as portable and embedded systems.

The DS1233-15/T&R is a member of the Power Management IC (PMIC) family of Supervisors, which includes a range of integrated circuit (IC) devices used to monitor and supervise the power states in electronic systems. The devices are available in logic-compatible, low- and high-voltage combinations, with functions ranging from watching single supply voltages to monitoring multiple supplies and enabling low voltage brownout detect.

The DS1233-15/T&R is one of the products in the PMIC Supervisors family, specifically designed for applications where levels and step-up voltage surges need to be monitored. Its working principle is based on a high-gain comparator that is set to activate a manual reset signal when it detects that a supply voltage has dropped below a reference threshold. This ensures that the power reset signal is always active during system power up.

The DS1233-15/T&R has an adjustable input voltage range of 2.5 to 4.5 V with a hysteresis level of 150 mV. It has an output current capability of up to ?? mA and it can provide an output voltage of up to 15 V. It features two Precision Timing Circuits (PTC) pins that can be used to set up reset delay times from tens of milliseconds up to several minutes, allowing the device to monitor different power sources for its supply current level.

The DS1233-15/T&R is suitable for both portable and embedded applications due to its low cost and easy implementation. It is ideal for applications such as on-board power regulation, cellular phones and other handheld devices, as well as voltage monitoring systems. Furthermore, its versatile features makes it suitable for a variety of digital systems, display systems and embedded MCUs.

Overall, the DS1233-15/T&R is a reliable and cost-effective device that offers protection against over-current or under-voltage situations, thus ensuring a safe and reliable system operation. With its wide voltage range and a hysteresis level of 150 mV, it can provide an output voltage of up to 15V, making it a reliable choice for applications that require reliable, robust power monitoring and adjustment.
