High Current PROFET TM
Smart High-Side Power Switches
One Channel 12-14-16 mW
T h e B T S 5 0 1 2 S D A , B T S 5 0 1 4 S D A , B T S 5 0 1 6 S D A are single
channel high-side power switches (from 12 to 16 mW), housed in PG-TO252-5
(DPAK 5 pin) RoHS compliant packages.
The devices have all current sense and provide an embedded set of protection
and diagnostic features, including ReverSaveTM, a function which causes the power
transistor to switch on in case of reverse battery mode, reducing power dissipation.
An optimized current limitation characteristic adjusts the maximum current
according to the supply voltage, making the devices particularly suitable to handle
the in-rush current of lamps.
Through the current sense pin, it is possible to diagnose, with a defined fault
signal, such events like overload operation, over temperature and/or short circuit
shutdown.
Protection Functions
■■ Short circuit protection with latch
■■ Overload protection
■■ Multi-step current limitation
■■ Thermal shutdown with restart
TM
■■ ReverSave , channel switches on in case
of reverse polarity
■■ Overvoltage protection
(including load dump)
■■ Loss of ground protection
■■ Loss of Vbb protection (with external
diode for charged inductive loads)
■■ Electrostatic discharge protection (ESD)
Diagnosis Functions
Proportional load current sense
■■ Defined fault signal in case of:

Pin-to-pin compatibility and identical functionality enable scalability by RDS(ON) and
–– Overload operation
related parameters; scalability is extended to the existing BTS 61xxD family.
–– Overtemperature shutdown
