DESCRIPTION
· The PCA9521 is a monolithic bipolar IC designed for bus buffering in I2C-bus, SMBus, PMBus, and similar systems.
· It extends bus load limits by buffering SCL and SDA lines, supporting up to 400 pF at 400 kHz.
· It features an enable function for bus isolation and controlled start-up, ideal for systems with removable components.
· Supports bus level translation from 1.8 V to 10 V, ensuring compatibility across diverse technologies.
· Provides fast response times, eliminating glitches without requiring rise-time accelerators.
FEATURES
· Dual, bidirectional unity gain buffer.
· Fast switching times for operation above 1 MHz.
· Supports I2C-bus, SMBus, PMBus, and IPMB standards.
· Enable pin for disconnecting bus segments.
· Low standby current and noise susceptibility.
· 6 mA static pull-down capability for wide bus compatibility.
· Operating voltage range: 2.7 V to 5.5 V.
· Bus voltage range: 1.8 V to 10 V.
APPLICATIONS
· Bus buffering in I2C-bus, SMBus, and PMBus systems.
· Systems with removable components, such as telecommunications racks.
· Interfacing systems with different voltage levels and technologies.
· Controlled start-up in diverse component and load environments.
