Description
The M63151FP is a driver and controller for use with three-phase brushless motor. A DMOS element with high
withstand voltage and low levels of switching loss is used on each output. Acceleration and deceleration inputs are
operable at TTL levels.
Features
• Power-supply voltage (max.): 30 V
• Output current (max.): 2.5 A
• RDS (typ.): 140 Ω (total of the upper and lower DMOS FETs)
• Built-in chip circuit for preventing through current in commutation
• Built-in chip comparator for current detection
• Buil-in chip overheating protection circuit
• Built-in chip motor-lock protection circuit
Applications
• OA equipment such as LBPs, copiers, and fax machines
