NEXPERIA NCA9535PWJ

NCA9535PWJ 일반적인 설명

NCA9535PWJ is a versatile GPIO expander suitable for I²C-bus/SMBus applications, offering 16 bits of General Purpose Input/Output (GPIO) expansion within a wide voltage range of 1.65 V to 5.5 V. With its interrupt capabilities, this expander is designed to meet the needs of various applications, providing an elegant solution for situations requiring additional IOs while minimizing interconnections, such as in ACPI power switches, sensors, push buttons, LEDs, and fan control. Featuring 8-bit input, output, configuration, and polarity inversion registers, the NCA9535PWJ allows for extensive customization based on specific requirements. The open-drain interrupt output becomes activated when any GPIO changes, offering efficient monitoring and control of the device. Furthermore, the three address pins A0, A1, and A2 enable configuration of the I²C bus slave address, allowing up to eight devices to share the same I²C-bus/SMBus. With its power-on reset function and device state machine, the NCA9535PWJ ensures reliable and consistent performance, making it an ideal choice for a wide range of GPIO expansion applications
