PCA9553DP/02规格书详情
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 masters (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 masters 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.
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
PCA9553DP/02属于集成电路(IC) > LED 驱动器。恩智浦半导体公司制造生产的PCA9553DP/02LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列,可通过标称固定电压的电源为负载(通常为发光二极管)提供电流,并且电流可控。它与用于电压调节的类似产品的主要区别在于,这类器件提供较低的反馈电压(以提高系统能效),而且通常可对器件工作点进行外部控制,可在照明应用中用于实现调光功能。
