PCA9550D,112

PMIC LED Drivers provide solutions that allow LED devices, usually requiring a constant and predictable amount of power, to be controlled. The PCA9550D,112 is a product contained within the PMIC LED Drivers portfolio. It is a 1-bit bidirectional voltage-level translator commonly used in LED applications. It features high-level voltage translation and two input/output enable controls.

The PCA9550D,112 device is a single-channel level translator that supports logic-level translation between 0.7V and 3.6V. The operation of the current is slew-rate-limited when driving high-capacitance loads, providing improved system robustness. It also provides two active-low output enable pins that allow independent control of the outputs and enable dynamic control of the risetime for improved system performance. The device is available in the SOT-23-5 package.

The PCA9550D,112 can be used in applications that require level translation between two different logic families, such as from LVTTL to HSTL or from 3.3V to 5V. Its low-current configuration is ideal for space-constrained designs, making it well-suited for space-saving displays and for use in portable devices where full support for power management is required. Additionally, it is also suitable for applications that require high-level voltage translation.

The PCA9550D,112 device is designed to translate signals between two logic families, specifically between 0.7V and 3.6V logic. It includes two input/output enable pins that allow independent control of the input and output, allowing the user to control the rise and fall times of the outputs with predictable operation. Furthermore, the PCA9550D,112 includes a slew-rate-limited current buffer to ensure robust operation when driving large capacitance loads.

The PCA9550D,112 can be used for various applications, such as for display and keyboard backlighting, to control LEDs in backlight systems. It is also useful for driving the logic in a variety of other display applications, such as digital signage, kiosks and gaming machines. Furthermore, it is suited for applications where power management is critical, such as in battery-powered mobile devices.

In summary, the PCA9550D,112 is a single-channel voltage-level translator designed for LED applications. It provides low-current operation and two input/output enable pins to allow independent control of the outputs. The PCA9550D,112 features slew-rate-limited current buffer to ensure robust operation when driving large capacitance loads.
