DS1819CR-10/T&R is a type of PMIC – Supervisors from Maxim Integrated. It is an advanced reset and power management circuit (PMC) that can provide optimal power for numerous applications, such as automotive and industrial applications. By combining a low-cost, 20MHz oscillator and an internal reset generator with robust voltage regulator functions, DS1819CR-10/T&R provides a reliable and cost-effective solution for power system design.

Working in conjunction with a 3.3V or 5V power supply, DS1819CR-10/T&R ensures proper reset conditions of the application’s processor. The built-in watchdog timer (WDT) helps to detect a lockup condition of the application, and the integrated reset generator triggered by the WDT activates the reset signal whenever the processor stalls. The PMC monitors the system current to detect overloads, and allows for overcurrent protection and soft-start functions.

The voltage regulator circuitry provided by the DS1819CR-10/T&R provides an output voltage range from 0.9V to 5V, with an output current of up to 300 mA. It also supports low-dropout voltage (LDO) and boost mode for increasing input voltage, with a switchable output power stage for better power efficiency. When used in combination with the integrated reset signals, this circuitry can further reduce the amount of over-voltage and over-current risks to the device and its power supply.

DS1819CR-10/T&R also features built-in power sequencing, which helps to ensure that application’s processor receives proper power at the right times. This feature allows the reset signals to be triggered at predetermined times, based on the events that occur in the application. This prevents any unexpected system crashes and reduces the amount of time and money spent on debugging and servicing the system.

As mentioned above, DS1819CR-10/T&R can be used in a variety of applications. The automotive sector can use DS1819CR-10/T&R as a reset and power management unit to control power-up/power down sequences in engine management systems. It is also suitable for use in industrial applications such as UPS systems, security systems, automation controllers, and telecommunications systems.

In summary, DS1819CR-10/T&R is an advanced reset and power management circuit (PMC) from Maxim Integrated. It enables engineers to achieve reliable, cost-effective and energy-saving solutions for many applications, especially automotive and industrial applications. DS1819CR-10/T&R offers power sequencing, integrated reset signals, robust voltage regulator functions and over-current protection, which makes the product a perfect choice for designers looking to optimize their device efficiency and reliability.
