Philips Semiconductors Product specification
7 N-channel 80 mΩ FET array
enhancement mode MOS transistors
FEATURES
• High-speed switching
• No secondary breakdown
• Very low on-state resistance.
APPLICATIONS
• Driving high performance three phase brushless
DC motors.
DESCRIPTION
Seven enhancement mode MOS transistors in a 24-pin
plastic SOT340-1 (SSOP24) package. Six of the
transistors are in three half-bridge configurations.
CAUTION
The device is supplied in an antistatic package.
The gate-source input must be protected against static
discharge during transport or handling.
