8 / 30 page  Design notes VT5366 8/30 3.4 Driving the navigation LED The VT5366 provides an output (TRK_LED) to drive the LED that is used to illuminate the mousing surface. This output is active HIGH but cannot be used to drive the navigation LED directly. An external NPN bipolar transistor is recommended as shown in the reference schematic ( Figure 6). The maximum current through the LED is controlled by a resistor (R1 on the Reference Schematic). Note: The navigation LED, controlled by the VT5366, is used in a non-continuous mode. The duty cycle of the LED is varied by the exposure controller inside the VT5366 and has a maximum value of 40 % (on very dark surfaces). |
