PCA9551D - Brand New NXP Semiconductors IC Chips
-
DESCRIPTION
The PCA9551 LED Blinker blinks LEDs in I2C-bus and SMBus applications where it is necessary to limit bus traffic or free up the I2 C Master’s (MCU, MPU, DSP, chipset, etc.) timer. The uniqueness of this device is the internal oscillator with two programmable blink rates.
FEATURES
•8 LED drivers (on, off, flashing at a programmable rate)
•2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.148 Hz and 38 Hz (6.74 and 0.026 seconds)
•Input/outputs not used as LED drivers can be used as regular GPIOs
•Internal oscillator requires no external components
•I2C-bus interface logic compatible with SMBus
•Internal power-on reset
•Noise filter on SCL/SDA inputs
•Active-LOW reset input
•8 open drain outputs directly drive LEDs to 25 mA
•Edge rate control on outputs
•No glitch on power-up
•Supports hot insertion
•Low stand-by current
•Operating power supply voltage range of 2.3 V to 5.5 V
•0 to 400 kHz clock frequency
•ESD protection exceeds 2000 V HBM per JESD22-A114,
150 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
•Latch-up testing is done to JESDEC Standard JESD78 which exceeds 100 mA
•Packages offered: SO16, TSSOP16, HVQFN16 -
