The PCA9553DP/01,118 from NXP Semiconductors is a versatile 4-bit I2C-bus LED driver designed for applications requiring controlled LED blinking and general-purpose I/O expansion. This device features an internal oscillator with two programmable blink rates, allowing for flexible control of LED flashing frequency and duty cycle, ranging from 0.172 Hz to 44 Hz.
Key electrical specifications include 4 open-drain outputs, each capable of driving LEDs up to 25 mA per bit, with a maximum package sink current of 100 mA. The device operates over a wide supply voltage range of 2.3 V to 5.5 V and supports I2C bus speeds up to 400 kHz. Unused I/O bits can be utilized as regular GPIOs, enhancing its utility.
Packaged in an 8-TSSOP or 8-MSOP, the PCA9553DP/01,118 is designed for surface mounting. It includes features like power-on reset, noise filters on SCL/SDA inputs, and controlled edge rates to minimize ground bounce, ensuring reliable operation. The device is suitable for I2C-bus and SMBus applications where limiting bus traffic or freeing up the master controller is necessary.
