Silicon Monolithic Integrated Circuit
7 x 7 Matrix LED DRIVER for Mobile Phone
BH6948GU
Highly effective Charge Pump circuit that can be switched 1 time, 1.5 times,
and 2 times pressure automatically. (190mA / MAX)
7-channel LED DRIVER that can contorol PWM
(IoMAX = 31mA/ch, Current step = 1mA)
7-channel PMOS-SW controlled with 1/8TDMA
It is possible to make 49(7X7) LED shine by PMOS-SW and the LED driver
SPI Interface
Wafer Level CSP pacage for space constrained applications
62pin (4.1mm×4.1 mm height = 1.0mm-max)
