PMIC (Power Management Integrated Circuit) is an integrated circuit that provides a wide range of power and energy management functions, such as regulating power supply voltage, managing power supply current, generating and managing system clock signals and voltage references, and controlling power on/off sequences. Voltage Reference is a subsystem of the PMIC, providing a stable and precise reference voltage for other parts of the PMIC.
ZHT431C01STZ Voltage Reference is a low-power low-noise shunt regulator specifically designed for PMIC solutions. It features a unique architecture that allows it to reduce the power consumption and noise of the voltage reference, while maintaining high accuracy and low cost. The ZHT431C01STZ operates from a wide input voltage range of 3V to 17V, providing the flexibility required for a wide variety of PMIC applications.
The ZHT431C01STZ’s main application field is in providing a bias voltage reference for a wide range of PMICs. It can be used in voltage regulator modules (VRMs), buck regulators, linear regulators, and other voltage-regulation solutions based around PMICs. It is also suitable for applications such as low-voltage power supplies, programmable logic controllers (PLCs), embedded systems, and other high-performance motion control systems. The ZHT431C01STZ is designed to provide the necessary accuracy and stability for these applications, and can be used with its low-power operation and low-noise characteristics.
The ZHT431C01STZ works by controlling the flow of current out of its output pin. The control is based on the input voltage of the device, and the reference voltage of the device. The output current is controlled by a simple voltage-controlled current source (VCCS) architecture. This architecture uses an on-chip voltage reference to create a stable output voltage, and then uses a series of current mirrors to provide a fine control of the output current. The mirrors are adjustable through a digital control port, allowing the device to be adjusted to a wide variety of different reference voltages.
In summary, the ZHT431C01STZ Voltage Reference is a low-power, low-noise, high-accuracy shunt regulator designed for providing a bias voltage reference to a wide range of PMICs. It works by controlling the flow of current out of its output pin using a VCCS architecture, allowing it to be adjusted to a wide variety of different reference voltages. Its wide input voltage range, low power consumption and low noise characteristics make it an ideal choice for a wide range of PMIC solutions.
