I²C-Interfaced 16-Port, Level-Translating GPIO and LED Driver with High Level of Integrated ESD Protection

Status: Active
Series: MAX7304
RoHS: Unknown
View Datasheet Manufacturer Site View Pricing & Stock

The MAX7304 consists of 16 port GPIOs, with 12 push-pull GPIOs and four open-drain GPIOs configurable as PWM-controlled LED drivers. The device supports a 1.62V to 3.6V separate power supply for level translation. An address-select input (AD0) allows up to four unique slave addresses for the device. Each GPIO can be programmed to one of the two externally applied logic voltage levels. PORT15–PORT12 can also be configured as LED drivers that feature constant-current sinks and PWM intensity control with the internal oscillator. The maximum constant-current level for each open-drain LED port is 20mA. The intensity of the LED on each open-drain port can be individually adjusted through a 256-step PWM control. The port also features LED fading. The same index rows and columns in the device can be used as a direct logic-level translator. The device is offered in a 24-pin (3.5mm x 3.5mm) TQFN package with an exposed pad, and a small 25-bump (2.159mm x 2.159mm) wafer-level package (WLP) for cell phones, pocket PCs, and other portable consumer electronic applications. The device operates over the -40°C to +85°C extended temperature range.
