HIP9021IB INTERSIL [Intersil Corporation], HIP9021IB Datasheet - Page 4

• Manufacturer Part Number: HIP9021IB
• Description: Portable Battery Drive/Torque Controller for N-Channel MOSFETs in Motor Control Systems
• Manufacturer: INTERSIL [Intersil Corporation]

NOTE: The timing diagrams relate to the delay output framed pulse and show the time duration of the delay pulse “framed” inside of the gate
pulse. The framed pulse duty cycle and delay, in percent, are measured in reference to the gate pulse which is set at 50% duty cycle. The
Delay output framed pulse delay is one-half of the difference of the gate pulse width minus delay output framed pulse width.
