Power management integrated circuits (PMICs) are essential components used in a wide variety of applications in which power monitoring, voltage control, and management of power supplies are needed. Supervisors are a type of PMICs that provide monitoring and protection of critical systems and power rails. One particular supervisor IC, the MAX6467XS32D3/V+T, is a low-power, highly integrated supervisor IC with an integrated voltage regulator to support a wide variety of market applications.

The MAX6467XS32D3/V+T is designed to monitor power rails in automotive and industrial applications where special protection is required. The device monitors and protects the power rails from overvoltage, undervoltage, and over current conditions. It works by monitoring key system voltages, such as the voltage regulator output and the battery voltage. When the voltage reaches an upper or lower threshold, or when a current limit is exceeded, the device signals the system for corrective action.

The integrated dual regulator makes the device suitable for a wide variety of applications that require a combination of voltage regulation and protection/supervision. The device includes two regulators, configured in a buck-boost configuration, that are capable of providing up to 3.2A and 5A of output current respectively. The regulators operate over a wide input voltage range of 4.5V to 32V and a wide output voltage range of 0.6V to 28V. They also feature input current and output current protection, overcurrent warning, thermal shutdown, and configurable output voltage.

The MAX6467XS32D3/V+T also includes two integrated non-voltage sensing (NVS) comparators that provide overvoltage and undervoltage protection. The NVS comparators monitor the input voltage and compare it with the adjustable upper and lower thresholds. If the input voltage exceeds the upper threshold or drops below the lower threshold, the NVS comparator trips and sends a signal to the system controller for corrective action. The device also provides integrated overcurrent protection and thermal shutdown.

The MAX6467XS32D3/V+T is suitable for a wide variety of applications, including automotive infotainment, industrial and medical systems, and other scenarios where protection and supervision of power rails are needed. The device’s low power consumption, small size, and integrated features make it an ideal choice for cost-sensitive and space-constrained applications. In addition, the MAX6467XS32D3/V+T is available in a 64-pin QFN package and is RoHS compliant.
