82375SB datasheet

 

Description

The 82375EB/SB PCI-EISA Bridge (PCEB) provides the master/slave functions on both the PCI Local Bus and the EISA Bus. Functioning as a bridge between the PCI and EISA buses, the PCEB provides the address and data paths, bus controls, and bus protocol translation for PCI-to-EISA and EISA-to-PCI transfers. Extensive data buffering in both directions increases system performance by maximizing PCI and EISA Bus efficiency and allowing concurrency on the two buses. The PCEB’s buffer management mechanism ensures data coherency.

The PCEB integrates central bus control functions including a programmable bus arbiter for the PCI Bus and EISA data swap buffers for the EISA Bus. Integrated system functions include PCI parity generation, system error reporting, and programmable PCI and EISA memory and I/O address space mapping and decoding. The PCEB also contains a BIOS Timer that can be used to implement timing loops. The PCEB is intended to be used with the EISA System Component (ESC) to provide an EISA I/O subsystem interface.

ECN3053F datasheet

 

Description

The ECN3053F drives a 3-Phase Motor Bridge with 3 TOP and 3 BOTTOM Arms, Push-Pull Output Drivers controlled by 6 CMOS inputs. Built in a High Voltage Dielectric Isolation Process, this Latch-Up Free IC can directly drive 6 IGBT or MOSFET gates in 3-Phase Brushless DC and Induction Motor Bridges. The TOP Arms can Boot Strap bias at up to 620VDC (Breakdown). An on-chip OpAmp allows Custom, Low, Over Current (OC) trip voltages so as to minimize Sense Resistor power dissipation in High Wattage applications. The TOP and BOTTOM Arms are Under Voltage (UV) protected.
