Datasheet Brief KTS1640, KTS1641 For full datasheet, click HERE. Load Switch with OVP and Reverse Polarity Protection Features Brief Description Wide input operating range from 6V to 40V The KTS1640 and KTS1641 are low-resistance, electronically controlled load switches, with enhanced DC Input protection features, used to protect loads from abnormal Low resistance MOSFET Switch typ. 41m power supply or load problems. Operating from a wide Reverse Polarity Protection to -28V input supply voltage of between 6V and 40V, the KTS1640 Fixed over-voltage protection and KTS1641 protect the system from reverse input Fixed: 27V 0.8V or 20.3V 0.8V supplies down to -28V. Fast OVP response time typ. 360ns Continuous output current up to 6A Integrating two N-Channel MOSFETs, the device includes Over-temperature Protection with Auto-Retry fixed over-voltage protection of 27V (KTS1640) or 20.3V Open drain fault flag (KTS1641) along with over-temperature protection with Shutdown pin with low shutdown current auto-retry. Following an over-voltage condition only, Voltage Input detection output KTS1640 and KTS1641 will automatically resume Input ESD protection to IEC61000-4-2 (Level 4) operation, when the over-voltage condition is removed. Contact: 8kV An ENABLE pin allows the MOSFET switch to be enabled Air: 15kV or disabled, placing the device in a low current shutdown Other pins HBM: 2kV mode. System monitoring is provided by a fault Pb-free TDFN44-12 package FLAG. -40C to +85C operating temperature range To inform the system that the battery or power supply is Applications connected, BDET mirrors the input voltage less the drop across the reverse battery protection MOSFET and Reverse Power Supply Protection sources up to a maximum of 120mA Telecom/Server/Networking System Further protection includes over-temperature shutdown Industrial and Medical Systems and the input pin is fully ESD protected to comply with the Portable Instrumentation IEC61000-4-2 (Level 4) specification. The KTS1640 and KTS1641 are packaged in an advanced, fully green compliant, TDFN44-12 package.
