Function
Pin Voltage
Selects pin 2 input: CK2 if high; DIR if low (see V_TH = 2.5 V typ
timing diagrams)
CK2 or DIR input (see timing diagrams)
CK1 input (see timing diagrams)
Reference value for 3-phase output current
and Ct charge/discharge current
V_TH = 2.5 V typ
V_TH = 2.5 V typ
4.8 V typ
No connection
Time constant for PWM carrier frequency
Voltage programming input to DAC (LSB)
No connection
V_TH = 2.5 V typ
Voltage programming input to DAC
Voltage programming input to DAC (MSB)
DAC output
V_TH = 2.5 V typ
V_TH = 2.5 V typ
Regulated output
4.8 V typ (@I = 2 mA)
Output enable: low enables PWM output
phases U, V, and W; high gives high
impedance
V_TH = 2.5 V typ
Current feedback
0 V min, 5.0 V max
Phase-W lower-arm output
