6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
VM Power supply voltage –0.3 65 V
VOUTx Output voltage –0.3 65 V
VCLAMP Clamp voltage –0.3 65 V
nFAULT Output current 20 mA
Peak clamp diode current 2 A
DC or RMS clamp diode current 1 A
Digital input pin voltage –0.5 7 V
nFAULT Digital output pin voltage –0.5 7 V
Peak motor drive output current, t < 1 μS Internally limited A
Continuous total power dissipation See Thermal Information
TJ Operating virtual junction temperature –40 150 °C
Tstg Storage temperature –60 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±3000 V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±1000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

6.3 Recommended Operating Conditions

MIN NOM MAX UNIT
VM Power supply voltage 8.2 60 V
VCLAMP Output clamp voltage(2) 0 60 V
IOUT Continuous output current SOIC package(1), TA = 25°C Single channel on 1.5 A
Four channels on 0.8
HTSSOP package(1), TA = 25°C Single channel on 2
Four channels on 1
(1) Power dissipation and thermal limits must be observed.
(2) VCLAMP is used only to supply the clamp diodes. It is not a power supply input.
