Preliminary Datasheet
MBI5038
16-Channel Constant Current LED Driver with
Features
Error Detection/ Power Saving Mode/ Current Gain
16 constant-current output channels
Constant output current range: 3~45mA
- 3~45mA @ 5V supply voltage
- 3~30mA @ 3.3V supply voltage
- 3~25mA @ 5V/3.3V supply voltage in mSSOP(GM) package
Compulsory error detection
- Data-independent full panel detection
- Error detection current: small current during 700ns
- Programmable detection current
- Individual LED open- and short-circuit detection
- Leakage and short to ground diagnosis
- Pre-settable threshold voltage for short-circuit detection and
leakage diagnosis
- Thermal protection
Power saving modes to reduce supply current of LED driver to 150uA
- 0-Power mode
Excellent output current accuracy,
- Between channels: <±2.5% (max);
- Between ICs: <±3% (max)
Fast response to achieve uniform output current,
OE (min.): 40ns (VDD=5V, IOUT=20mA)
Staggered delay of output, preventing from current surge
30MHz clock frequency
Schmitt trigger input
Package MSL Level : 3
