The DS1816R-10+T&R is a popular product in the Power Management Integrated Chip or PMIC supervisory family.

PMIC supervisors play an important role in an electronic system, they ensure proper power supply sequencing and allow devices to operate correctly under a wide range of conditions. From battery powered devices, such as wearables and remote controls, to high powered data center components. PMIC supervisors are essential for any electronic system.

The DS1816R-10+T&R is a product specifically designed for use in automotive, industrial, and military applications. It is a CMOS IC featuring integrated supervisor and reset functions with adjustable starts and asserted power-on reset delay. It monitors power supply rails, providing configurable logic and reset mechanism to maintain the correct state of the device.

The device integrates an advanced supervisor circuit, startup path control, watchdog timer (WDT), refresh circuit, an external signal control circuit, and an active low reset output. This helps to ensure the proper functioning of electronic systems, particularly in rugged and harsh environment settings.

The DS1816R-10+T&R moves power in a quick and efficient manner. It ensures proper sequencing, spreads the load across multiple voltage rails, controls the power-up sequence, and validates power up before allowing a system to proceed. Additionally, the device supports two independent power rails, with separate starts and power-on reset delays. The main power-down and power-cut functions are configurable with two external resistor links.

The DS1816R-10+T&R is designed to operate at both low and high temperatures, within -40 °C to +125 °C. This features adds to the reliability of any system using this device in operation. However, the highest accuracy and performance are ensured only at room temperature.

The device has an integrated watchdog timer (WDT) with time-out period adjustable through external resistor. The WDT then can be used as a reset circuit in situations where the system should be knocked out of its current state and restarted. Additionally, the WDT can be used as a live-test circuit to detect unintended software hangs or other anomalies.

The device also features overflow protection and refresh circuits, both designed to maintain stable operation in noisy, inactive environments. When the DS1816R-10+T&R is coupled with other PMIC devices for other applications, the circuit usually performs better than when used alone. This is due to the further level of stability and accuracy the other components provide.

The DS1816R-10+T&R is a useful and reliable PMIC supervisor designed to ensure correct power sequencing and operation in a wide range of applications. It offers benefits such as flexibility, accuracy, and robustness to any system it is used in. It also takes into account expected conditions and monitors the power supply rail to keep the system running correctly.
