MPC17529EL MOTOROLA [Motorola, Inc], MPC17529EL Datasheet - Page 9

• Manufacturer Part Number: MPC17529EL
• Description: 0.7 A Dual H-Bridge Motor Driver with 3.0V/5.0V Compatible Logic I/O
• Manufacturer: MOTOROLA [Motorola, Inc]

Typical Application
applying the gate voltage to the C
source, be sure to connect it via a resistor equal to, or greater
than, R
CEMF Snubbing Techniques
damaging CEMF spikes induced when commutating currents in
inductive loads. Typical practice is to provide snubbing of
voltage transients by placing a capacitor or zener at the supply
terminal (VM) (see
