Power management integrated circuits (PMICs) are a type of semiconductor device that helps control the flow of power within circuits. The PT7M6837ID3TBEX is a PMIC supervisor from STMicroelectronics, which belongs to the Supervisors category. It is designed to provide power protection and management for electronic systems. The device is specifically suitable for applications that require low-current consumption, extended temperature ranges, and small solution size.

The PT7M6837ID3TBEX is a highly integrated device that includes a number of different functional blocks. It includes integrated, adjustable system reset, power-on reset and sticky reset functions, as well as a system watch timer and voltage supervisor. The device also features an auto-sequencing circuit that ensures correct system power/clocking startup. This ensures that all components of a system turn on and off in the correct order.

The system reset and power-on reset functions of the PT7M6837ID3TBEX are designed to ensure that all components turn on and off in the correct sequence. The integrated, adjustable reset threshold generates a reset signal when the power supply voltage decreases below a pre-set voltage. The reset signal forces the system to reset, which prevents any undesirable behavior. The sticky reset signal is generated when the system power is turned off, which forces the system to enter into a known state and clears any stuck bits.

The integrated system watch timer on the PT7M6837ID3TBEX has adjustable delay time settings that can be used to reset the system at regular intervals. This provides system stability and prevents any potential problems associated with corrupted data or stuck bits. The voltage supervisor ensures that the voltage to the system never decreases below a pre-set threshold, thus providing circuit protection.

The innovative auto-sequencing circuit on the PT7M6837ID3TBEX manages power-up and power-down sequences, ensuring that the system always turns on and off in the correct sequence. It provides hysteresis to the power supply voltage and prevents any unexpected voltage rises or drops from occurring. The auto-sequencing circuit supports up to six states, from power-off to power-up.

The PT7M6837ID3TBEX provides reliable, cost-effective power protection and management for embedded applications. The device is optimized for low current consumption, extended temperature ranges, and small package sizes. It is ideal for embedded applications such as industrial and automotive systems.
