Product details
Overview
DRV8313RHH from Texas Instruments is a triple ½-H-bridge motor driver IC designed for three-phase brushless DC (BLDC) motor control, solenoid actuation, and brushed DC loads. It delivers 2.5-A peak output current per channel, operates from 8 V to 60 V VM supply, integrates a 3.3-V/10-mA LDO regulator, and features independent channel enable (ENx) and input (INx) control. It is used in precision motion systems requiring compact, high-voltage motor drive with integrated protection.
For engineers reviewing the DRV8313RHH datasheet, DRV8313RHH pinout, DRV8313RHH application, or DRV8313RHH equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and electrical specifications, real-world application mappings, and two rigorously cross-checked alternative parts - all grounded in TI's SLVSBA5D revision D documentation and official package data.
Technical Context
The DRV8313RHH implements three independent N-channel half-H-bridge drivers, each with dedicated PGND terminals enabling per-channel low-side current sensing. Its charge-pump circuit generates gate-drive voltage above VM to fully enhance high-side FETs, supporting operation up to 60 V with typical rDS(on) of 0.24 Ω (HS/LS, TJ = 25°C).
Integrated protection includes undervoltage lockout (VUVLO = 6.3–8 V), overcurrent detection (IOCP = 3–5 A, deglitch tOCP = 5 µs), and thermal shutdown (TTSD = 150–180°C), all signaled via open-drain nFAULT. An uncommitted comparator (COMPP/COMPN/nCOMPO) supports configurable current limiting or auxiliary analog monitoring.

FAQ
What is the maximum continuous operating voltage for DRV8313RHH?
The DRV8313RHH supports a recommended operating VM supply range of 8 V to 60 V. Its absolute maximum VM rating is 65 V, but sustained operation above 60 V risks exceeding safe junction temperature or violating SOA limits. Designers must ensure proper decoupling and thermal management when operating near the upper limit, especially at elevated ambient temperatures.
Does DRV8313RHH include internal current sensing?
No, the DRV8313RHH does not integrate current-sense amplifiers. However, it provides dedicated PGND1, PGND2, and PGND3 pins to support external low-side shunt resistors per channel. The uncommitted comparator (COMPP/COMPN/nCOMPO) can be configured to monitor shunt voltage - enabling user-defined current limiting or feedback without additional ICs.
Can DRV8313RHH drive brushed DC motors?
Yes, the DRV8313RHH can drive brushed DC motors by configuring two of its ½-H bridges as a full H-bridge per motor. For example, OUT1 and OUT2 can control one motor, while OUT3 remains unused or drives a second smaller load. Each ½-H bridge supports bidirectional control, braking, and coasting via INx/ENx logic states defined in Table 1 of the datasheet.
What is the purpose of the RSVD pin on DRV8313RHH?
Pin 18 on the DRV8313RHH (RHH package) is marked RSVD (Reserved) and has no internal connection. Per TI's SLVSBA5D revision D datasheet, this pin must be left unconnected - neither tied to GND nor routed. It was introduced in revision D to replace the former GND function and is not intended for any electrical or thermal role.
How does the DRV8313RHH enter and exit sleep mode?
The DRV8313RHH enters sleep mode when nSLEEP (Pin 27) is driven logic-low, disabling the charge pump, outputs, and V3P3 regulator - reducing VM supply current to 500–800 µA. It exits sleep mode automatically when nSLEEP returns high; full functionality resumes after ~1 ms, during which internal clocks and regulators stabilize. No nRESET assertion is required.
