Test Conditions

VENABLE = 0.8 V, VBRAKE = 2.0 V

VENABLE = 2.0 V, VMODE = 0.8 V

VBRAKE = 0.8 V

VENABLE = VMODE = VBRAKE = 2.0 V

VENABLE = 0.8 V

VENABLE = 2.0 V, VMODE = 0.8 V

VBRAKE = 0.8 V

VENABLE = VMODE = 2.0 V

Operating

VIN = 2.0 V

VIN = 0.8 V

VCC = 3.0 V to 3.6 V

VCC = 4.5 V to 5.5 V

VREF = 0 V to 1 V

VREF = 0 V
