(1) V
HR
refers to the required voltage headroom necessary to drive the LEDs. See Table 7 for the appropriate V
HR
value.
(2) V
LED
refers to the maximum voltage drop across the external LED (at maximum LED current) connected between the TXP and TXN pins
(in H-bridge mode) and from the TXP and TXN pins to LED_DRV_SUP (in the common anode configuration).
(3) V
CABLE
refers to voltage drop across any cable, connector, or any other component in series with the LED.
