Overview
The BD62321HFP-TR is a high-current H-bridge driver designed for brushed DC motors, manufactured by Rohm Semiconductor. It supports a wide power supply voltage range of 6V to 32V and delivers a maximum output current of 3A. The device features an integrated MOS transistor output stage controlled via PWM input signals operating between 20kHz and 100kHz. Key electrical specifications include a maximum Vcc of 36V, typical output on-resistance of 1Ω, and an operating temperature range from -25°C to 85°C. The component is housed in an HRP7 package (TO-263-8 variant) with dimensions of 9.395x10.54mm.
Feature Summary
- Integrates a single H-bridge driver circuit with low standby current consumption.
- Includes built-in cross-conduction prevention circuits to ensure safe operation.
- Provides comprehensive output protection against overcurrent, overvoltage, overheating, undervoltage, and short circuits to both power and ground.
Applications
- Media players
- Brushed DC motor control systems
Procurement Notes
Verify the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as Yes. Ensure the application does not involve automotive equipment, as this product is explicitly not recommended for such use. Check that the required voltage and current parameters align with the 6V-32V and 3A limits respectively before procurement.
Selection Notes
Select this component for applications requiring a single brushed DC motor drive with integrated protection. It is suitable for designs needing PWM control within the 20kHz-100kHz range. Consider its pin compatibility with the BD623XHFP series if upgrading existing designs. Do not select for automotive environments due to explicit manufacturer restrictions.
Part Context
This part belongs to the BD623XHFP series of H-bridge drivers. It is classified as a standard-level product currently in active production status. The device is categorized under Power Management ICs, specifically Motor Drivers and Controllers. It utilizes Power MOSFET technology for its output stage.
Replacement Considerations
The BD62321HFP-TR is pin-compatible with other members of the BD623XHFP series, facilitating straightforward replacement or upgrade paths within that family. Verify exact suffixes for packaging differences when substituting.
