LX432CSC

PMIC (Power Management Integrated Circuit) is a type of integrated circuit that provides reliable power control to electronic systems, particularly microprocessors. One type of PMIC which stands out is voltage reference – the LX432CSC model.

The LX432CSC is a voltage reference designed primarily for use in automotive, space, and avionic applications where low power consumption is desired. It integrates an Operational Amplifier with an adjustable Output Voltage Reference, allowing the user to configure the Output Voltage to any level between 0 and 5V.

The LX432CSC features a compact design with a small number of external components making it ideal for space-constrained applications. The stable and low-jitter integrated oscillator further increases its suitability for certain applications. The device can also be used as a temperature monitor, as it includes an internal temperature sensor.

The LX432CSC is a low-current device, operating at less than 260µA typically, even at maximum output current. This enables it to provide reliable power control with minimal power consumption. Additionally, the device allows the user to program the output voltage level, making it ideal for various types of voltage control tasks.

The output voltage of the LX432CSC is controlled by the Op-Amp, and the output of the Op-Amp is compared to the reference voltage level. When the output voltage is equal to the reference voltage level, the output of the Op-Amp is low. However, when the output voltage is greater than the reference voltage level, the output of the Op-Amp is high, resulting in the output voltage being increased. Conversely, when the output voltage is lower than the reference voltage level, the output of the Op-Amp is low, resulting in the output voltage being decreased.

The user can adjust the reference voltage level by using an external voltage divider connected to the control input. The output voltage can then be programmed by adjusting the reference voltage level and the gain of the Op-Amp.

The LX432CSC is an ideal voltage reference solution for automotive, space, and avionic applications. It is capable of providing reliable power control with minimal power consumption, thanks to its low-current operation. Additionally, it allows the user to program the output voltage level, making it ideal for various types of voltage control tasks. Finally, its compact design and low-jitter oscillator further increase its suitability for certain applications.
