Kinetic Technologies Launches AEC-Q100 Automotive Load Switch for Power Transient Protection
KTS1642Q supports reverse battery, over-voltage and transient protection for automotive ECUs, ADAS, infotainment and telematics systems.
Kinetic Technologies, a Cyient Semiconductors company and a leader in high-performance analog and mixed-signal semiconductor solutions, announced the KTS1642Q. This AEC-Q100 qualified automotive load switch is specifically designed to help automotive electronic systems withstand the demanding electrical conditions defined by ISO 16750-2 and ISO 7637-2.
"Meeting automotive power transient requirements has become increasingly challenging as vehicles incorporate more sophisticated electronic systems. The KTS1642Q integrates the critical protection functions needed to help designers address ISO 16750-2 electrical stress conditions and ISO 7637-2 transient requirements while reducing component count, minimising power loss, and accelerating system qualification."
– Jan Nilsson, CTO, Kinetic Technologies
Modern vehicles expose ECUs to reverse battery, cold crank, jump-start, load dump, and inductive switching transients. The KTS1642Q helps designers build robust power architectures that withstand these events while protecting sensitive downstream electronics.
Operating from 4V to 40V, the device provides reverse battery protection to -28V, fixed 20.3V over-voltage protection, typical 360ns OVP response, 41mΩ on-resistance, 6A output current, over-temperature protection with auto-retry, battery detection, and fault reporting.
When used with appropriate external TVS diodes, the KTS1642Q supports ISO 7637-2 transient requirements while helping designers address the electrical stress conditions of ISO 16750-2.
