PMIC (Power Management Integrated Circuit) is a type of integrated circuit that can provide all necessary power regulation, protection and monitoring functions in a single device. Supervisors are a subset of the PMIC family, and are designed to provide reset and other system stability functions to ensure the reliability and safety of the system operation. The DS1810R-10/T&R is a dual-channel reset supervisor designed to provide reset and power-on reset functions in a variety of applications.

The main advantages of using the DS1810R-10/T&R are the small size and low cost. The device comes in a 2x1.5mm, 8-pin 0.75 mm pitch “U-Package” that provides the highest performance in a SOT-23 standard solution. The device requires minimal external components for operation, allowing for easy assembly and cost savings.

The DS1810R-10/T&R reset supervisor is designed to operate from a wide +2.8V to +5.5V supply. Once the power supply level has been determined, the reset process can be enabled through a single logic-level control signal. When the control signal is first applied, the device monitors the power supply voltage and charges an external capacitor connected to the RESET#- pin. When the voltage reaches the internal reset threshold, the voltage is discharged and the RESET# pin is pulled low, triggering a power-on reset.

The DS1810R-10/T&R supervisor features an on-chip push button debouncing circuit which eliminates the need for external hysteresis. The reset debounce time can be programmed to either 10 ms or 25 ms. In addition, the DS1810R-10/T&R includes an open drain output, which can be used to drive an external N-channel MOSFET for power supply reset or power-on reset.

The DS1810R-10/T&R reset supervisor can be used in a variety of applications, including application processors and microcontrollers, memory systems, fitness trackers, cellular handsets, embedded systems and many other applications that require reliable power supply reset or power-on reset. In these applications, the device can be used to protect against power failure or brown-out conditions, provide power-on reset to initiate the system boot, and to reset the processor in case of a system fault or after successful system codes execution.

The DS1810R-10/T&R reset supervisor can also be used to ensure the proper functioning of safely critical systems by providing a low impedance reset function to quickly reset the system in the event of an emergency. This is particularly important in systems that require instant reset of the system, such as motor applications and medical systems.

The DS1810R-10/T&R reset supervisor is also suitable for power supply sequencing applications, as it can be set to generate up to three outputs at preset delays. Moreover, the device is available in both an extended temperature range marking (-40 °C to +85 °C) and a commercial temperature range marking (0 °C to +70 °C).

In summary, the DS1810R-10/T&R reset supervisor is a reliable and cost-effective solution for a variety of power-related functions. Its small size, low cost and wide voltage range make it an ideal choice for a wide range of applications and systems. With its easy-to-use control interface, and its wide array of functions, the DS1810R-10/T&R is an ideal choice for any application that requires reliable power management.
