Product Summary
Package
| Operating Voltage Vbb(on) | 5.0...34V | |
| Active channels | one | two parallel |
| On-state Resistance RON | 30mΩ | 15mΩ |
| Nominal load current IL(NOM) | 5.5A | 8.5A |
| Current limitation IL(SCr) | 24A | 24A |
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
