MBI5037
16-Channel Constant Current LED Driver with
Silent LED Error Detection and Power Saving Modes
Product Description
MBI5037 is an enhanced 16-channel constant current LED sink driver with advanced error detection functions and
smart power-saving modes. MBI5037 succeeds MBI5026 and also exploits PrecisionDrive™ technology to
enhance its output characteristics. Furthermore, MBI5037 uses the concept of Share-I-O™ technology to make
MBI5037 package compatible with MBI5026 and extend its advanced functions, such as silent LED open circuit
detection, silent LED short detection, leakage diagnosis, and temperature warning. With the Share-I-O™ technique,
the printed circuit board originally designed for MBI5026 may be also applicable to MBI5037, if the OE is
controllable. In addition, MBI5037 features two power saving modes: sleep mode and 0-Power mode to increase
the power efficiency. Therefore, MBI5037 is especially suitable for LED traffic sign and message sign applications.
MBI5037 provides “compulsory silent error detection”. Once the dedicated command is issued, all of the current
output ports will be turned on in about 700ns interval with small current. The image will not be impacted since the
turn-on duration and current are so small. MBI5037 may detect all of the current output ports and report the LED
error status without comparing original data. Moreover, the settable threshold voltages for short-circuit detection
and leakage diagnosis may comply with the variation of different LED forward voltage. Additionally, to ensure the
system reliability, MBI5037 is built with thermal error flag to prevent IC from over temperature (160°C).
MBI5037 also features two power saving modes: sleep mode and 0-Power mode. Both modes reduce the supply
current of MBI5037 to 200uA to save the power. Flexible for different applications, sleep mode can be issued by
command, while 0-power mode is automatically activated when all the output data are 0. For the power saving
purposes, MBI5037 is especially designed to save the supply current of LED drivers when most LEDs on LED
traffic signs and message signs are usually turned off.
MBI5037 contains a 16-bit shift register and a 16-bit output latch, which convert serial input data into parallel output
format. At MBI5037 output stages, sixteen regulated current output ports are designed to provide uniform and
constant current sinks with small current variation between current output ports for driving LEDs within a wide
range of forward voltage (VF) variations. Users may adjust the output current from 3mA to 80mA with an external
resistor Rext, which gives users flexibility in controlling the light intensity of LEDs. MBI5037 guarantees to endure
maximum 17V at the output ports. Besides, the high clock frequency up to 30MHz also satisfies the system
requirements of high-volume data transmission.
