STMicroelectronics L6234PD Three Phase Brushless DC Motor Driver 7-42V 5A

STMicroelectronics L6234PD Three Phase Brushless DC Motor Driver provides a 5A output current and a 7V to 42V supply voltage range for controlling three-phase brushless DC motors.

The STMicroelectronics L6234PD is a triple half-bridge motor driver integrated circuit for three-phase brushless DC motors. It uses BCD-multi-power technology, combining isolated DMOS power transistors with CMOS and bipolar circuitry on a single chip. The output DMOS transistors are capable of sustaining high currents, and the maximum RMS current is primarily constrained by the device's thermal dissipation capabilities.

Key Features

• Integrated protection including thermal shutdown and cross-conduction prevention
• Fast free-wheeling diodes (intrinsic diodes) that facilitate rapid current decay
• Independent input and enable functions for each half-bridge
• TTL-compatible logic inputs
• Output stage capable of driving loads up to 52V with a continuous output current of 5A

Specifications

• IC type: Half-bridge motor driver
• Number of outputs: 3
• Output current: 5A
• Output voltage: 52V
• Supply voltage range: 7V to 42V
• Weight: 6.713 gm
