6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
VM Power supply voltage –0.3 11.8 V
Digital input pin voltage –0.5 7 V
xISEN pin voltage –0.3 0.5 V
Peak motor drive output current Internally limited A
TJ Operating 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) ±4000 V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±1500
(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

TA = 25°C (unless otherwise noted)
MIN NOM MAX UNIT
VM Motor power supply voltage range(1) 2.7 10.8 V
VDIGIN Digital input pin voltage range –0.3 5.75 V
IOUT RTY package continuous RMS or DC output current per bridge(2) 1.5 A
(1) RDS(ON) increases and maximum output current is reduced at VM supply voltages below 5 V.
(2) VM = 5 V, power dissipation and thermal limits must be observed.
