9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

9.1 Application Information

The ISO7830x device is a high-performance, triple-channel digital isolator with 5.7-kVRMS isolation voltage. The

device comes with enable pin which can be used to put the outputs in high impedance for multi-master driving

applications and reduce power consumption. The ISO7830x device uses single-ended CMOS-logic switching

technology. The supply voltage range is from 2.25 V to 5.5 V for both supplies, VCC1 and VCC2. When designing

with digital isolators, keep in mind that because of the single-ended design structure, digital isolators do not

conform to any specific interface standard and are only intended for isolating single-ended CMOS or TTL digital

signal lines. The isolator is typically placed between the data controller (that is, μC or UART), and a data

converter or a line transceiver, regardless of the interface type or standard.

9.2 Typical Application

ISO7830F can be used with Texas Instruments' mixed signal micro-controller, gate driver, transformer driver and

voltage regulator to create an isolated MOSFET/ IGBT drive circuit. Figure 20 shows an implementation of

isolated dual channel gate driver
