SP7616: Low Side LED Driver

many LEDs are shorted, and the VLED voltage

becomes to high, making the part dissipates too

much power, the over temperature protection will

shut the part off when the die temperature reaches

150

0C. For further information refer to the over-

temperature protection section.

THEORY OF OPERATION

Over-temperature protection

The SP7616 offers Over-temperature protection.

When the die temperature rises above 150

0C the

output drivers are shut off. The output current will

self recover when the temperature drops below the

trip point with the preset hysteresis of 15

0C. Thus a

part that shut off at 150

0C will not try to restart

unless the die temperature is below 135
