ISL88694
ISL88694 is SMBus Accelerator (SMA) manufactured by Renesas.
feature makes the switching behavior invariant for all power supply voltages between 2.7V and 5.5V.
A noise filter on each channel prevents the circuit from responding to input transitions that do not exceed a voltagetime threshold. To activate the boost circuit, the input must exceed VTRIPL by 100Vns (typical) (See Figure 10).
The SMA permits operation of the bus at frequencies up to 100k Hz, despite the capacitive loads of multiple devices and/or long PC board traces. Enhanced ESD protection on the accelerator pins are guaranteed to withstand 8k V ESD (HBM) events.
The SMBus Accelerator provides an essential function in SMBus applications because of distributed capacitance of SMBus and multiple device input capacitances at various nodes. By incorporating SMA, systems using SMBus or I2C can reliably increase their bus load without the risk of data loss.
