Brief Description
The KTS1640 and KTS1641 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 KTS1640
and KTS1641 protect the system from reverse input
supplies down to -28V.
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.
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 120mA
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 KTS1640 and KTS1641 are packaged in an advanced,
fully green compliant, TDFN44-12 package.
