General description

The PCA9553 LED blinker blinks LEDs in I²C-bus and SMBus applications where it is necessary to limit bus traffic or free up the I²C-bus master's (MCU, MPU, DSP, chip set, etc.) timer. The uniqueness of this device is the internal oscillator with two programmable blink rates. To blink LEDs using normal I/O expanders like the PCF8574 or PCA9554, the bus master must send repeated commands to turn the LED on and off. This greatly increases the amount of traffic on the I²C-bus and uses up one of the master's timers. The PCA9553 LED blinker instead requires only the initial set-up command to program BLINK RATE 1 and BLINK RATE 2 (i.e., the frequency and duty cycle). From then on, only one command from the bus master is required to turn each individual open-drain output ON, OFF, or to cycle at BLINK RATE 1 or BLINK RATE 2. Maximum output sink current is 25 mA per bit and 100 mA per package.

Any bits not used for controlling the LEDs can be used for General Purpose Parallel Input/Output (GPIO) expansion.

Power-On Reset (POR) initializes the registers to their default state, all zeroes, causing the bits to be set HIGH (LED off).

Due to pin limitations, the PCA9553 is not featured with hardware address pins. The PCA9553/01 and the PCA9553/02 have different fixed I²C-bus addresses allowing operation of both on the same bus.

Features

4 LED drivers (on, off, flashing at a programmable rate)
2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.172 Hz and 44 Hz (5.82 seconds and 0.023 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
4 open-drain outputs directly drive LEDs to 25 mA
Controlled edge rates to minimize ground bounce
No glitch on power-up
Supports hot insertion
Low standby current
Operating power supply voltage range of 2.3 V to 5.5 V
0 Hz 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 JEDEC Standard JESD78 which exceeds 100 mA
Packages offered: SO8, TSSOP8 (MSOP8), HVSON8
