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 |
---|---|---|---|---|
Open detect | J1 | LED1 open | LED1 string connect to OUT1 | LED1 string open |
J3 | LED2 open | LED2 string connect to OUT2 | LED2 string open | |
Short detect | J2 | Single LED short | Short 3 LEDs in LED1 string | 3 LED series in LED string |
J4 | LED string short | Short 3 LEDs in LED2 string | 3 LED series in LED string | |
Device enable | J5 | EN | The device is enabled (EN connected to SUPPLY via a resistor) | The device is disabled (EN is floating) |
PWM dimming input | J6 | PWM1 | Enable PWM1(PWM1 connected to SUPPLY through a resistor) | Disable PWM1 or use external control signal |
J7 | PWM2 | Enable PWM2(PWM2 connected to SUPPLY through a resistor) | Disable PWM2 or use external control signal | |
Fault option | J8 | FAULT | One fails, others on | Use external control signal |
