8-bit Fm+ I2C-bus LED driver - # of Addresses: 126 ; Enable: yes ; I2C-bus: 1000 kHz; I2C-bus interface: Fast Mode Plus 30 mA SDA outputs for 4000 pF bus ; Max Sink Current per bit: 25 mA; Max Sink Current, per package: 200 mA; Number of bits: 8 ; Operating temperature: -40~85 Cel; Operating voltage: 2.3~5.5 VDC; PWMs: 9 (8 x 97 kHz dim and 1 x 97 kHz dim or 24 Hz to 10.73 sec blink); Package: SOT163-1 (SO20); Container: Tape reel smd
The PCA9634D,118 can sink or source up to 25mA per output pin, and up to 100mA total for all outputs combined.
The PCA9634D,118 can be configured for 8-bit or 10-bit PWM resolution by setting the RES bit in the MODE1 register. For 8-bit resolution, set RES=0, and for 10-bit resolution, set RES=1.
The OE pin is an active-low input that enables or disables all output drivers. When OE is low, all outputs are enabled, and when OE is high, all outputs are disabled.
The PCA9634D,118 can be reset by pulling the RST pin low for at least 1ms. This resets all registers to their default values.
The PCA9634D,118's internal oscillator can operate up to 25MHz.
