Brief Description

The KTS1640Q and KTS1641Q are low-resistance,

electronically controlled load switches, with enhanced

protection features, used to protect loads from abnormal

power supply or load problems. Operating from a wide

input supply voltage of between 6V and 40V, the

KTS1640Q and KTS1641Q protect the system from

reverse input supplies down to -28V.

Integrating two N-Channel MOSFETs, the device includes

fixed over-voltage protection of 27V (KTS1640Q) or 20.3V

KTS1641Q) along with over-temperature protection with

auto-retry. Following an over-voltage condition only,

KTS1640Q and KTS1641Q will automatically resume

operation, when the over-voltage condition is removed.

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

FLAG.

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 500mA

Further protection includes over-temperature shutdown

and the input pin is fully ESD protected to comply with the

IEC61000-4-2 (Level 4) specification.

The KTS1640Q and KTS1641Q are packaged in an

advanced, fully green compliant, TDFN44-12 package.
