The EVM provides some jumpers for designers to conveniently validate the device. Table 2-2 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 | |
J5 | LED3 open | LED3 string connect to Out2 | LED3 string open | |
Single LED short detect | J2 | LED1 string Single LED Short | Short one LED in LED1 string | 3 LED series in LED1 string |
J4 | LED2 string Single LED Short | Short one LED in LED2 string | 3 LED series in LED2 string | |
J6 | LED3 string Single LED Short | Short one LED in LED3 string | 3 LED series in LED3 string | |
PWM dimming input | J7 | PWM1 | Enable PWM1 (PWM1 connected to SUPPLY via a resistor) | Disable PWM1 or use external control signal |
J8 | PWM2 | Enable PWM2 (PWM2 connected to SUPPLY via a resistor) | Disable PWM2 or use external control signal | |
J9 | PWM3 | Enable PWM3 (PWM3 connected to SUPPLY via a resistor) | Disable PWM3 or use external control signal | |
Device Enable | J6 | EN | The device is enabled (EN connected to SUPPLY via R9) | The device is disabled (EN floating) |
Off-board application | J1 | GND and GND2 connection | LED board ground GND2 connects to LCM board ground GND1 | Disconnect GND1 and GND2 |
J2 | Ictrl off-board | Ictrl connect to 544 ohm with 160-mV Vsns | Ictrl floating with 400-mV Vsns |
