Load switch guards automotive power rails

Kinetic Technologies’ KTS1642Q AEC-Q100-qualified load switch protects automotive loads from abnormal power-supply or load conditions. When used with the appropriate external TVS diodes, the device supports ISO 7637-2 transient requirements while helping designers address the electrical stress conditions of ISO 16750-2.

Operating from 4 V to 40 V, the KTS1642Q integrates two N-channel MOSFETs with 41-mΩ on-resistance and delivers 6 A of continuous output current. It provides reverse-battery protection to -28 V, fixed 20.3-V overvoltage protection with a typical 360-ns response time, overtemperature protection with auto-retry, battery detection, and a fault flag output. Input ESD protection meets IEC 61000-4-2 Level 4, with ±2-kV HBM ESD protection on other pins per AEC-Q100-002.
The load switch operates over a temperature range of -40°C to +125°C and is supplied in a 4×4-mm TDFN. The KTS1642AQGDV-TR features an active-high enable, while the KTS1642QGDV-TR features an active-low enable. Both versions are available now.
