Working Principles

The MAX6961ATH+T is an LED display driver that utilizes a serial interface (I2C) to communicate with an external microcontroller. It supports both common-cathode and common-anode displays, providing flexibility in display configuration.

The device features 16 output channels, each capable of driving up to 35mA of current. Individual current control allows precise adjustment of brightness for each LED segment. The built-in PWM brightness control further enhances the visual quality of the display.

The MAX6961ATH+T includes error detection circuitry, which monitors the status of each output channel. In case of any fault or open-circuit condition, the device reports the error through the interrupt output pin (INT).

Additionally, the MAX6961ATH+T can be cascaded to drive larger displays by connecting multiple devices together. This simplifies the design and reduces the complexity of driving multi-digit or multi-segment displays.
