X4165S8I-4.5A

The X4165S8I-4.5A is a low power voltage supervisor providing simple monitoring of microprocessor power rails and system reset. It is designed and manufactured using advanced BiCMOS process technology, and features four main operating thresholds: 3.2V, 3.3V, 3.3V-BYPASS, and 5.0V. The operating range is 0.86V to 6.0V, the reset pin is 0°C to +70°C, and the output discharge is low: 0.3mA at 20V. In addition, the shutdown pin is 0°C to +85°C and the open drain output discharge is low: 0.55mA at 10V. The X4165S8I-4.5A is an ideal device for a variety of applications and can be used to monitor the voltage levels of a range of systems and a variety of processor-oriented systems, including those used in automotive and commercial industrial settings.

The X4165S8I-4.5A comes with many features and benefits, providing effective methods of voltage supervision and reset. It has a typical reset valid time of 140ms, fault hysteresis of 0.5V and provides accurate overtemperature fault detection with a minimum delay of 1.2ms. It also offers flexibility to customize settings according to user needs. The X4165S8I-4.5A is designed with a delay time before reset, which can be adjusted with external capacitor settings to ensure accurate reset pulse timing.

The typical application field of the X4165S8I-4.5A includes a variety of power supply applications, such as voltage monitoring and surge protection for microprocessors, power switches, and other integrated circuits, as well as reset control for complex systems. It is also used in industrial process control, automotive, and telecommunications systems. The X4165S8I-4.5A is also suitable for multi-rail systems, where different voltage levels require supervision and reset.

The operating principle of the X4165S8I-4.5A is simple and straightforward. When the voltage on either of the two inputs is below its respective threshold, the output state is logic "0" and the reset/fault latch is activated. If both inputs remain below their respective thresholds, the reset/fault latch will remain active until the power is removed or an active-high reset signal is applied. When the voltage on both inputs goes above the respective thresholds, the output state is logic "1" and the reset/fault latch is disabled. In addition, the device includes a shut down input that when used disables the reset/fault latch.

The X4165S8I-4.5A is a powerful and versatile PMIC – supervisors designed to provide reliable voltage supervision and reset control in a variety of applications. With its features and especially its adjustability and stability it offers cost-effective and trusted protection of your system. With its high temperature range, fast response, and built-in hysteresis, the X4165S8I-4.5A is the perfect choice for any voltage monitoring and reset protection application.
