General Description
• N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input,
diagnostic feedback and proportional load current sense monolithically integrated in Smart SIPMOS
technology.
• Providing embedded protective functions
Applications
• µC compatible high-side power switch with diagnostic feedback for 12V and 24V grounded loads
• All types of resistive, inductive and capacitve loads
• Most suitable for loads with high inrush currents, so as lamps
• Replaces electromechanical relays, fuses and discrete circuits
Basic Functions
• CMOS compatible input
• Undervoltage and overvoltage shutdown with auto-restart and hysteresis
• Fast demagnetization of inductive loads
• Logic ground independent from load ground
Protection Functions
• Short circuit protection
• Overload protection
• Current limitation
• Thermal shutdown
• Overvoltage protection (including load dump) with external
resistor
• Reverse battery protection with external resistor
• Loss of ground and loss of Vbb protection
• Electrostatic discharge protection (ESD)
Diagnostic Functions
• Proportinal load current sense
• Diagnostic feedback with open drain output
• Open load detection in OFF-state with external resistor
• Feedback of thermal shutdown in ON-state

7) At supply voltage increase up to Vbb= 4.7 V typ without charge pump, VOUT ≈Vbb - 2 V
8) Supply voltages higher than Vbb(AZ) require an external current limit for the GND and status pins (a 150 Ω
resistor in the GND connection is recommended). See also VON(CL) in table of protection functions and
circuit diagram page 9.
9) Measured with load; for the whole device; all channels off
10) Add IST, if IST > 0
11) Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as "outside" normal operating range. Protection functions are not
designed for continuous repetitive operation.

Timing diagrams
Both channels are symmetric and consequently the diagrams are valid for channel 1 and
channel 2

the current limit of the device.
