DRV8251  
SLVSFZ6 – DECEMBER 2021  
DRV8251 4.1-A Brushed DC Motor Driver with Integrated Current Regulation  
1 Features  
3 Description  
•
•
•
N-channel H-bridge brushed DC motor driver  
4.5-V to 48-V operating supply voltage range  
Pin-to-pin, RDS(on), voltage, and current sense/  
regulation variants (external shunt resistor and  
integrated current mirror)  
The DRV8251 device is an integrated motor driver  
with N-channel H-bridge, charge pump, current  
regulation, and protection circuitry. The charge  
pump improves efficiency by supporting N-channel  
MOSFET half bridges and 100% duty cycle driving.  
– DRV8870: 6.5-V to 45-V, 565-mΩ, shunt  
– DRV8251: 4.5-V to 48-V, 450-mΩ, shunt  
– DRV8251A: 4.5-V to 48-V, 450-mΩ, mirror  
– DRV8231: 4.5-V to 33-V, 600-mΩ, shunt  
– DRV8231A: 4.5-V to 33-V, 600-mΩ, mirror  
High output current capability: 4.1-A Peak  
PWM control interface  
Supports 1.8-V, 3.3-V, and 5-V logic inputs  
Integrated current regulation  
Low-power sleep mode  
The DRV8251 implements a current regulation feature  
by comparing the analog input VREF and the voltage  
across a current-sense shunt resistor on the ISEN  
pin. The ability to limit current can significantly  
reduce large currents during motor startup and stall  
conditions.  
•
•
•
•
•
A low-power sleep mode achieves ultra-low quiescent  
current draw by shutting down most of the internal  
circuitry. Internal protection features include supply  
undervoltage lockout, output overcurrent, and device  
overtemperature.  
– <1-µA at VVM = 24-V, TJ = 25°C  
Small package and footprint  
– 8-Pin HSOP with PowerPAD™, 4.9 × 6.0 mm  
•
•
The DRV8251 is part of a family of devices which  
come in pin-to-pin, scalable RDS(on) and supply  
voltage options to support various loads and supply  
rails with minimal design changes. See Section 5 for  
information on the devices in this family. View the full  
portfolio of brushed motor drivers on ti.com.  
Integrated protection features  
– VM undervoltage lockout (UVLO)  
– Latched overcurrent protection (OCP)  
– Thermal shutdown (TSD)
