PMIC - Voltage Regulators - Special Purpose

CHL8328-00CRT integrated circuit is a special purpose voltage regulator manufactured by Microchip, Inc. It provides two Voltage Regulator (VR) outputs, 1A and 2A, in which these two outputs support output voltage down to 0.22V with minimum distortion and low dropout for loads up to 2.5A. Moreover, CHL8328-00CRT outputs have temperature coefficient and fast transient response of less than 20us, even with minimum 5 days fast transient response time.

The device is designed for power monitor, portable audio applications and other applications which require low noise and high efficiency. It can support up to 1A and 2A load currents with output voltage down to 0.22V and can quickly detect an over-voltage in an error threshold window, allowing for quick recovery and protection of system components.

CHL8328-00CRT voltage regulator performs its functions through two separate stages. The first stage is the power monitoring stage, in which it can check the load current and output voltage, and detect if any of them exceeds the pre-defined upper or lower limit. If over-voltage or over-current is detected, it will activate the second stage, which is the protection mechanism. The second stage will switch the output voltage to a lower value, and discontinue the current supply to the load.

CHL8328-00CRT voltage regulator provides a high voltage margin for the power monitoring stage, ensuring that the system components are fully protected under all circumstances. Furthermore, the device is also rated for an operating temperature range of -40°C to 125°C, which it can operate and function effectively even in extreme temperatures.

In addition, CHL8328-00CRT voltage regulator comes with a low quiescent current of 250μA, allowing for better system performance and longer battery life. It has a wide input voltage range from 2.5V to 16.5V, and its power management feature allows the system to stay in low-power consumption condition when not in use. All in all, this integrated circuit can ensure highly reliable power delivery while saving energy.

Overall, CHL8328-00CRT voltage regulator has a wide range of applications in power monitor, portable audio and other devices needing low-dropout and high efficiency. It can effectively support load current up to 2.5A, and the two separate stages of the device can protect system devices from over-voltage or over-current. This integrated circuit also comes with features such as wide input voltage range, low quiescent current and power management, making it an excellent choice for energy-efficiency and reliable system performance.
