Product Overview
PCA9956BTWY is a 24-channel Fm+ I2C-bus 57mA/20V constant current LED driver. The PCA9956B is an I2C-bus controlled 24-channel constant current LED driver optimized for dimming and blinking 57mA Red/Green/Blue/Amber (RGBA) LEDs in amusement products. Each LED output has its own 8-bit resolution (256 steps) fixed frequency individual PWM controller that operates at 31.25kHz with a duty cycle that is adjustable from 0% to 99.6% to allow the LED to be set to a specific brightness value. An additional 8-bit resolution (256 steps) group PWM controller has both a fixed frequency of 122Hz and an adjustable frequency between 15Hz to once every 16.8 sec with a duty cycle that is adjustable from 0% to 99.6% that is used to either dim or blink all LEDs with the same value. Typical applications include amusement products, RGB or RGBA LED drivers, LED status information, LED displays, LCD backlights, keypad backlights for cellular phones or handheld devices.
- Operating power supply voltage (VDD) range from 3V to 5.5V
- Output current adjusted through an external resistor (Rext input)
- Output current accuracy (±6% between PCA9955B devices)
- 8MHz internal oscillator requires no external components
- Internal power-on reset and noise filter on SDA/SCL inputs
- No glitch on LEDn outputs on power-up and low standby current
- 5.5V tolerant inputs on non-LED pins
- ESD protection exceeds 4000V HBM per JESD22-A114
- 38 pin HTSSOP package
- Ambient temperature range from -40 to 85°C
