Power management integrated circuits (PMICs) are dedicated semiconductor ICs for managing the power budget of integrated circuit designs. These circuits primarily handle the energy requirements necessary to control specific operating conditions such as current, voltage, and temperature. PMICs are divided into four groups: voltage regulators, current regulators, power switches, and supervisors. The S-80933CLMC-G63T2U is a 3V, 3.3V Low Noise Input regulator and supervisor IC typically used in microprocessors, application processors and other system level components.

The S-80933CLMC-G63T2U is a supervisor device capable of monitoring and controlling the power states of multiple system rails. It is designed to ensure system power stability and optimum power consumption. It is also capable of detecting low voltage events and asserting an alert signal if needed. It incorporates a low noise, high efficiency regulator and current limiter for maximum power savings in light loads without compromising system reliability. The device also has built-in monitoring circuits for detecting brown-outs, overloads, and over-temperatures.

The S-80933CLMC-G63T2U was designed for use in GPU, image processor, and power control systems. Its integrated voltage regulator and current limiter provides stable and reliable power to critical components, reducing the power-related risks due to fluctuations in environmental conditions and component stress. It is also able to detect and protect sensitive components from sudden changes in power and voltage. Its low noise output and current limiting feature makes it ideal for continuous operation in portable and mobile applications.

The S-80933CLMC-G63T2U works by monitoring a single-rail voltage provided by a battery or external power supply. It then provides a stable regulated output voltage that can be adjusted using two external resistors. As with all PMICs, the device has several built-in protection mechanisms. These protections include brown-out, overload, over-voltage, over-temperature, and ESD protections. Its 3V, 3.3V voltage regulators provide up to 100mA and 300mA current, respectively.

The S-80933CLMC-G63T2U also features a low power spike rejection (LPSR) mode that can be enabled through an external pin. The LPSR mode reduces the ripple of an input voltage and maintains a lower noise level while still providing a stable output, making it ideal for low power applications. The device also features programmable over-voltage protection (OVP) with a range of 2.3V–3.6V. When OVP is detected, the output is held to its minimum voltage, allowing for system safety and reliability without external protection components.

Finally, the S-80933CLMC-G63T2U also features multiple monitoring circuits such as a power-on reset (POR), an over-current, and an over-temperature detection. The POR circuit helps to prevent system corruption on power-up or power-down. The over-current detection helps to protect against excessively high current flow and the over-temperature detection helps to protect the device from damage due to excessively high temperature. In addition, the device provides an interrupt output that can be used to alert the system of any low voltage or over-temperature alert.

In conclusion, the S-80933CLMC-G63T2U is a 3V, 3.3V Low Noise Input regulator and supervisor IC typically used in microprocessors, application processors and other system level components. Its integrated voltage regulator and current limiter offer efficient power delivery, low noise output, and current limiting features ideal for low power applications. It is a suitable device for mobile and portable applications as it has built-in monitoring mechanisms and protection features.
