T amb = 25 ° C; V VDD = 12 V; R IREF = 33 k ? ; V EN = V VDD and CPWM connected to a capacitor, unless otherwise speci?ed. All
voltages are measured with respect to signal ground (SGND, pin 10). SGND and PGND connected together. GL, GH,
COMM, NONFAULT and PWMD pins left open (unless otherwise speci?ed). Currents are positive when ?owing into the IC.
Parameters valid for all types (unless otherwise speci?ed).
