The EVM provides some jumpers for designers to conveniently validate the device. Table 3-3 shows the jumper map.
Function | Designator | Attached Function | With Shunt | Without Shunt |
---|---|---|---|---|
Device enable | J1 | EN | The device is enabled (EN connected to SUPPLY via a resistor) | The device is disabled (EN floating) |
PWM dimming input | J2 | PWM | Enable PWM (PWM connected to SUPPLY via a resistor) | Disable PWM or use external control signal |
Fault option | J3 | FAULT | One fails, others off | Use external control signal |
Open detect | J4 | LED open | LED string connect to out | LED string open |
Short detect | J5 | Single LED short | Short single LED in LED string | 3 LED series in LED string |
J6 | LED string short | Short all LEDs in LED string | 3 LED series in LED string |
