TECHNICAL NOTE

For brush motors

H-bridge drivers (18V max.) BD6220, BD6221, BD6222, BD6225, BD6226, BD6227 Overview These H-bridge drivers are full bridge drivers for brush motor applications. Each IC can operate at a wide range of power-supply voltages (from 3V to 36V), supporting output currents of up to 2A. MOS transistors in the output stage allow for PWM signal control, while the integrated VREF voltage control function of previous models offers direct replacement of deprecated motor driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design. Features 1) Built-in, selectable one channel or two channels configuration 2) Low standby current 3) Supports PWM control signal input (20k Hz to 100k Hz) 4) VREF voltage setting pin enables PWM duty control 5) Cross-conduction prevention circuit 6) Four protection circuits provided: OCP, OVP, TSD and UVLO

Applications VCR; CD/DVD players; audio-visual equipment; optical disc drives; PC peripherals; car audios; car navigation systems; OA equipments

Frequently Asked Questions

What voltage range can these H-bridge drivers operate at?

The ICs can operate across a wide power-supply voltage range, from 3V to 36V.

How is the motor speed controlled using this device?

You can control it using PWM signal input (20kHz to 100kHz). Additionally, the VREF pin allows for PWM duty cycle control.

What safety protections are built into these drivers?

Four protection circuits are provided: Overcurrent Protection (OCP), Overvoltage Protection (OVP), Thermal Shutdown (TSD), and Under Voltage Lockout (UVLO).

Are these suitable for systems requiring extreme reliability, like medical equipment?

No. For life-critical devices (e.g., aerospace or medical instruments), you must consult a sales representative before use.
