Features

Key Features

  • Thermal efficiency: eSOIC package delivers 2X lower thermal impedance, saving board space and simplifying design
  • Automatic thermal back-off: Temperature regulated, peak current limiting ensures continuous high availability operation
  • Real-time load current monitoring: Analog feedback current mirror feature used for motor control or load protection
  • Design-in simplicity: Integrated H-Bridge with charge pump, control, protection and four MOSFETs
  • High efficiency: 120 mΩ typical RDS(ON)
  • Load supply voltage 5 V to 36 V continuous operation, 42 V transient
  • Operation up to 5 A covering a wide range of applications.
  • 3 and 5 V TTL/CMOS compatible
  • Status flag output reports under-voltage, over-current, and over-temperature fault conditions
  • Output short-circuit protection (short to VPWR or GND)
  • Sleep mode with current draw < 20 μA
  • Parallel interface and input control
  • Ambient operating temperature -40 °C (Min), 85 °C (Max)
