The X4005S8IZ-4.5A is a PMIC-Supervisor that provides efficient power management and fault protection capabilities to enable safe, reliable and cost-effective system operations. The device offers several features that are suited for a wide range of applications, including handheld and portable devices, motor drive systems, computer/networking products, and electric/hybrid vehicles.

The X4005S8IZ-4.5A is an active reset supervisor, controlling an output signal based on five monitoring parameters: Brown-out detection (BOD), voltage comparator inputs (VCI), short circuit protection, over-temperature protection (OTP) and over-voltage protection (OVP). The device can operate in three different modes, depending on the external configuration: Brown-out mode, Voltage Constraint (VCon) mode, and Para-Para Reset mode. In all three modes, the output signal is asserted if any of the five monitoring parameters exceed their respective thresholds.

The BOD feature of the X4005S8IZ-4.5A prevents erroneous logic operation due to a voltage level below the minimum working threshold. This is accomplished by detecting if the voltage level drops below the VDET threshold and then resetting the part. The VCon mode of the device can be used to reduce power consumption by shutting down the system if the input voltage exceeds its operating limit. The OTP feature enables the device to shut down the system to prevent over-temperature related system damage.

The over-voltage protection feature prevents damage to the system if the input voltage exceeds its operating limit. The X4005S8IZ-4.5A uses a combination of active reset and output clamping to protect the system against over-voltage conditions. The short circuit protection feature of the device monitors the output and reset signals for a continuous short circuit condition, and operates in either a latching or non-latching mode depending on the external configuration.

The X4005S8IZ-4.5A can be used in many applications, including portable and embedded systems, motor control systems, and electric/hybrid vehicles. In these applications, the device provides reliable power management and fault protection to ensure safe and cost-effective system operations. In addition, the device’s wide range of monitoring parameters and operating modes give designers flexibility and ease of application.
