HOLTEK's LEDDriver introduces the HT1632C for direct push LED applications. The HT1632C is a characteristic gain version of the HT1632. It greatly improves the drive capability, IC power consumption, display uniformity, etc. It is more suitable for direct push LEDs. The HT1632C is especially suitable for applications such as fitness equipment, electronic darts, perpetual calendars, information displays and digital clocks.
HT1632C continues HT1632 specifications: operating voltage 2.4V ~ 5.5V, can drive 2 kinds of resolution LED panel (32 × 8 points and 24 × 16 points); with 16-order PWM brightness adjustment function; built-in 256kHz RC oscillator; Multiple sets of LEDs are connected in series to expand the number of display points; it includes DisplayRAM and serial interface mode supporting MCU.
In addition to the built-in 256kHz RC oscillation frequency, the HT1632C system's operating frequency allows the external clock to be used as the operating frequency of the system to increase system flexibility. The HT1632C drive current is increased to 250mA. When the product is applied, the LED can be directly pushed, no external transistor is needed, and the production cost is reduced.
The HT1632C's single integrated Segment and Common solutions make it easier for users to control the display and reduce the use of MCUI/O ports, as well as reduce peripheral hardware lines and components, greatly reducing the number and cost of ICs used by customers.
