PMIC - Supervisors

Power Management Integrated Circuits (PMICs) are a type of component used to monitor, regulate, and control current levels in electrical designs. PMIC Supervisors are a family of products used for power sequencing and to maintain a safe operating environment for electronic circuits. S-1011EAC-M6T1U4 is the newest addition to the Infineon Supervisors family, and it is designed to improve the safety and productivity of a wide range of applications across the mobile, automotive, and industrial markets.

Overview of S-1011EAC-M6T1U4 Application Field and Working Principle

S-1011EAC-M6T1U4 is a supervisor IC that monitors and controls the power supply, timing, and temperature of a power system. It supports up to 3-phase output circuits and a wide input range of 4.5V to 28V. The S-1011EAC-M6T1U4 features one configurable input pin, two configurable outputs, and one analog output pin. It also incorporates a master stand-by input and output, enabling the system to be placed in low power standby mode when required. At the heart of S-1011EAC-M6T1U4’s operation is a series of IP blocks, which are specifically designed to control currents, monitor under- and overvoltage conditions, monitor temperatures, and sequence the timing of power-up, power-down, and reset operations.

Voltage Superscalar Technology

S-1011EAC-M6T1U4 incorporates Infineon’s Voltage Superscalar Technology (VST), which is engineered to improve accuracy, reduce current leakage, and enable high system performance. VST is an optimization of the voltage scaling method used to control system power. By incorporating a high switching frequency, VST improves the efficiency of the system and significantly reduces on-state resistance and the power dissipated by the system.At the core of VST is an advanced current sensing system that monitors and controls the current in a power system. This current sensing system includes current sensing circuitry, temperature sensing circuitry, a voltage supervisor circuit, and analog circuitry. The current sensing circuitry is designed to detect the presence or absence of a current, and to measure the magnitude of the current. The temperature sensing circuitry monitors the temperature of the system and can be used to protect the system from overheating or other dangerous conditions. The voltage supervisor continuously monitors the voltage of the system and can be used to prevent the system from becoming overloaded. Finally, the analog circuitry in the current sensing system is used to monitor and control the current levels in the system.

Sequencing Techniques

S-1011EAC-M6T1U4 also includes two configurable sequencing techniques, a delay timer and a charge pump.The delay timer is used to sequence the timing of power-up and power-down operations in a system. The delay timer can be configured to provide a specific delay before the power-up and/or power-down operations are executed. This allows the system to determine when the power-up and power-down operations need to be executed in order to achieve the desired system performance.The charge pump is used to maintain the system voltage during system power up and down operations. The charge pump continuously monitors the system voltage and increases or decreases it in order to maintain a consistent voltage for the system. This prevents the system from becoming overloaded or underpowered due to changes in the input voltage.The combination of the delay timer and charge pump can be used to provide an extended power up and down sequence for systems that require more precise control over the timing and voltage of the power up and down operations.

Conclusion

S-1011EAC-M6T1U4 is the newest supervisor from Infineon, designed to provide a high level of safety and performance in numerous applications across the mobile, automotive, and industrial markets. The S-1011EAC-M6T1U4 features innovative Voltage Superscalar Technology, current sensing circuitry, and configurable sequencing techniques to ensure the accurate, safe, and efficient operation of a variety of power systems.
