7.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Voltage Supply voltage (VDD to GND) –0.3 6.5 V
Input voltage, except AINP and AINN pins(2) GND – 0.5 VDD + 0.5
Shunt-sense amplifier inputs (AINP and AINN pins)(3) GND – 6.0 VDD + 6.0
Current DRV1 and DRV2 pins (short-circuit current, IOS)(4) –300 300 mA
Shunt-sense amplifier input pins AINP and AINN –5 5
All remaining pins –25 25
Temperature Junction, TJ –50 150 °C
Storage, Tstg –65 150
(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.
(2) Input pins are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5 V beyond the supply rails must be current limited, except for the differential amplifier input pins.
(3) These inputs are not diode-clamped to the power-supply rails.
(4) Power-limited; observe maximum junction temperature.
