HOLTEK launch, HT1632C LED drive

HOLTEK (Group) LEDDriver for direct LED applications can be pushed out of the HT1632C. HT1632C is a characteristic gain version of the HT1632, in the driving power, IC power consumption, display uniformity and other characteristics are greatly improved, more suitable for direct push LED. HT1632C is especially suitable for fitness equipment, electronic darts, calendar, information display and digital clock and other products.

The continuation of HT1632 HT1632C specifications: working voltage 2.4V ~ 5.5V, LED panel can drive 2 resolution (32 x 8 and 24 x 16); with 16 order PWM brightness adjustment function; built-in 256kHzRC oscillator; multiple LED can be connected in series, expand the display points; serial interface with DisplayRAM and MCU support the.

HT1632C system operating frequency in addition to the built-in 256kHzRC oscillation frequency, and allows the external clock as the operating frequency of the system, increase system flexibility. HT1632C drive current increased to 250mA, the product can be directly pushed LED, without the need to plug in transistors, reduce production costs.

The integration of Segment and Common single HT1632C scheme, allowing users to more easily control the display screen and reduce the use of MCUI/O port, and can reduce the external hardware circuit and parts, greatly saves the quantity and cost of customers using IC.
