Operating from a wide input supply voltage of between 6V and 40V, the KTS1640 and KTS1641 protect the system from reverse input supplies down to -28V.<\/p>\n<p>Integrating two N-Channel MOSFETs, the device includes fixed over-voltage protection of 27V (KTS1640) or 20.3V (KTS1641) along with over-temperature protection with auto-retry. Following an over-voltage condition only, KTS1640 and KTS1641 will automatically resume operation, when the over-voltage condition is removed.<\/p>\n<p>An ENABLE pin allows the MOSFET switch to be enabled or disabled, placing the device in a low current shutdown mode. System monitoring is provided by a fault <span style=\"text-decoration: overline\">FLAG<\/span>.<\/p>\n<p>To inform the system that the battery or power supply is connected, BDET mirrors the input voltage less the drop across the reverse battery protection MOSFET and sources up to a maximum of 120mA<\/p>\n<p>Further protection includes over-temperature shutdown and the input pin is fully ESD protected to comply with the IEC61000-4-2 (Level 4) specification.<\/p>\n<p>The KTS1640 and KTS1641 are packaged in an advanced, fully green compliant, TDFN44-12 package.<\/p>\n\t    <a
