TPS7A4001 SBVS162A – MARCH 2011 – REVISED MARCH 2011 www.ti.com APPLICATION INFORMATION TRANSIENT VOLTAGE PROTECTION One of the primary applications of the TPS7A4001 is to provide transient voltage protection to sensitive circuitry that may be damaged in the presence of high-voltage spikes. This transient voltage protection can be more cost-effective and compact compared to topologies that use a transient voltage suppression (TVS) block.
