0V to 16V, Dual Hot-Swap Controller with 10-Bit
Current and Voltage Monitor and 4 LED Drivers
Table 53 shows LED State register. The LED State regis-
ter is a read-only register. When the LEDs are disabled,
the pins are configured as GPIOs. Applying an external
voltage below 0.4V sets the GPIOs low and, applying an
external voltage above 1.4V, sets the GPIOs high.
I 2 C Serial Interface
The MAX5970 features an I 2 C serial interface consist-
ing of a serial-data line (SDA) and a serial-clock line
Table 53. L ED State Register
(SCL). SDA and SCL allow bidirectional communication
between the MAX5970 and the master device at clock
rates from up to 400kHz. The I 2 C bus can have several
devices (e.g., more than one MAX5970, or other I 2 C
devices in addition to the MAX5970) attached simultane-
ously. The A0 and A1 inputs set one of nine possible I 2 C
addresses (see Table 54).
