As power solutions continuously evolve to meet the more stringent demands of modern designs, the Texas Instruments (TI) TPS386040RGPT has emerged as a viable choice. By integrating a variety of features into a single device, the TPS386040RGPT offers reliability, robustness and performance.

The TPS386040RGPT is a member of TI’s family of Programmable Monitors and Supervisors Device (PMIC). It is designed to protect digital logic and reduce system failures, while providing advanced features such as adjustable reset timing, power-on reset initialization and input logic voltage domain options. It offers a variety of reset options, including Fixed Reset Output, Programmable Duration, Multiple Voltage Domain Fault Detection, Low VCC Monitor and Brownout Detection.

At its core, the TPS386040RGPT is a supervised power system manager. It monitors the status of the motor, logic and system power, manages external power sequencing and protects the system from over current, over temperature, and transient events. The on-chip thermal sensor monitors the temperature of the system, providing additional protection for sensitive components.

The TPS386040RGPT is a versatile device and can be used in a variety of applications, such as clock synchronization, embedded system and power system management. It can also be used in automotive, industrial and medical applications. Due to its adjustable reset timing, it is suitable for use in slow startup applications and enables user programming of reset timing.

The TPS386040RGPT works in conjunction with the external power management integrated circuit (PMIC) to manage the power system. The PMIC provides the necessary current and voltage to the application, while the TPS386040RGPT supervises the power system’s status. It monitors the system for faults and, in the event of a fault, helps initiate corrective action.

When power is applied to the system, the TPS386040RGPT monitors the input voltage, compares it to a user-programmable voltage threshold and checks for brownout conditions. If the voltage is outside of the programmed range, the reset pin is triggered and will remain asserted until the proper input voltage is restored. The device also contains a precision temperature sensor which monitors the temperature to ensure proper operation and protects the application from overheating.

The TPS386040RGPT also includes multiple adjustable reset timeouts and a programmable reset function which allow for fault tolerance and flexibility. If any of the timeout periods expire, or if any fault condition is detected, the device will trigger the reset pin and initiate a system reset. This helps ensure the system operates in a safe and reliable manner.

The TPS386040RGPT can also be programmed to operate as a windowed supervisor, providing different reset thresholds for a range of input voltage levels. The reset window allows for higher tolerance for short transients and lower VDD values, ensuring improved system reliability.

The TPS386040RGPT is a versatile PMIC supervisory device, with a wide range of application areas, such as automotive, industrial and medical. It provides superior reliability and feature richness in a small package, while also helping to minimize system failures and minimize power utilization.
