Power Management Integrated Circuit (PMIC) is an important component of modern electronic systems. It is used for power gating, current measurement, voltage regulation and many other power management operations. Supervisors play an important part in PMICs by protecting against system reset. In some cases, it is even used for system initialization. The S-1000N45-I4T1U is one such supervisor IC specifically designed for Automotive Applications.
The S-1000N45-I4T1U is an automotive-grade voltage supervisor and monitoring IC from STMicroelectronics. It is designed for use in automotive electronic systems that require reliable power supply monitoring, power-on reset (POR) and system reset generation. The IC offers a comprehensive set of features including adjustable watchdog timer, power supply under-voltage protection and reset, overvoltage protection, N-MOS open drain output, low power supply current draw, voltage monitoring range of 0.8V to 2.44V and overcurrent detection.
The S-1000N45-I4T1U has several important applications in the automotive sector including engine control unit, airbag control unit, ABS and ESP systems, body computers, immobilizers and climate control units. This IC also has several features that enable it to provide an additional layer of protection, such as short circuit detection, brown out protection and cycle-by-cycle overcurrent protection. Additionally, the IC includes an adjustable reset voltage and an adjustable watchdog timer, which can be used to delay reset and ensure system stability.
The working principle of the S-1000N45-I4T1U is straightforward. It monitors the input voltage of the application and compares it to preset thresholds, set using external resistors. When the voltage drops below or rises above the thresholds, the IC initiates a reset or power-on cycle, respectively. When the voltage is within the set threshold range, the IC remains in an active state. This feature makes the S-1000N45-I4T1U highly reliable and suitable for automotive applications.
The S-1000N45-I4T1U is an automotive-grade voltage supervisor and monitoring IC providing reliable protection for microcontroller-based systems. It uses adjustable thresholds to monitor the input power supply, and in the event of an overvoltage or undervoltage condition, the IC will initiate a reset or power-on cycle, respectively. Furthermore, it includes features such as short circuit detection, brown out protection and cycle-by-cycle overcurrent protection, as well as an adjustable reset voltage and a watchdog timer. As a result, the S-1000N45-I4T1U is a powerful, reliable and cost-effective solution for power supply monitoring and protection in automotive applications.
