Product details
Overview
TB9080FG from Toshiba Electronic Devices & Storage Corporation is a 3-phase brushless DC motor controller IC with integrated gate driver for external N-channel MOSFETs, operating from 7–18 V supply, supporting sine-wave commutation, AEC-Q100 qualified, and featuring built-in 5 V main/sub regulators, Hall sensor interface, and comprehensive fault monitoring for automotive battery cooling fans.
For engineers reviewing the TB9080FG datasheet, TB9080FG pinout, TB9080FG application, or TB9080FG equivalent, key selection considerations include its 64-pin LQFP package, 8 MHz external oscillator requirement, PWM/analog speed control inputs (PSIG/ASIG), CW/CCW direction control, and integrated overcurrent/overtemperature/motor lock detection with diagnostic pulse output on DG pin.
Technical Context
The TB9080FG implements a digital sine-wave generation system using Hall sensor feedback (SUP/SUN/SVP/SVN/SWP/SWN) to compute rotor position and apply lead-angle compensation. Its internal logic uses an 8 MHz external crystal or ceramic oscillator (XIN/XOUT) as timing reference for PWM output at ~15.7 kHz and digital filter τ = 4.0 s for soft-start current limiting.
It integrates six high-side/low-side pre-driver outputs (OUP/OUN/OVP/OVN/OWP/OWN) with configurable dead-time correction (DT0/DT1), a DC/DC boost circuit (SWIN/SWDRV/VSW) generating ~VCC+12 V for high-side gate drive, and dual 5 V regulators - one main (VREG) with external PNP transistor and one sub-regulator (VSUB) for PSIG pull-up in sleep mode.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN32F0A | Integrated 32-bit ARM Cortex-M0 MCU + gate drivers; requires firmware development; no external oscillator needed (internal RC) | Best for designs needing closed-loop PID, field-oriented control (FOC), or custom diagnostics; higher design complexity | Select STSPIN32F0A when algorithmic flexibility and embedded processing are required; TB9080FG offers simpler, hardware-based sine-wave control with faster time-to-market. |
| MP6532 | 6-channel pre-driver only (no controller logic); requires external MCU for commutation; supports 100 V VDS MOSFETs | Suitable for high-voltage (>40 V) industrial BLDC systems; lacks integrated protection, regulators, or Hall interface | Choose MP6532 for high-voltage motor drives where full custom control is preferred; TB9080FG provides complete automotive-grade controller + driver in one IC. |

FAQ
What is the recommended external oscillator for TB9080FG?
The TB9080FG requires an external 8 MHz crystal or ceramic oscillator connected between XIN (Pin 14) and XOUT (Pin 16). The internal oscillator circuit includes a feedback resistor, so no external resistor is needed. Ceramic resonators meeting minimum drive level specifications are acceptable, and all timing parameters in the datasheet-including PWM frequency (~15.7 kHz)-are specified at this 8 MHz reference.
How does TB9080FG handle motor overcurrent protection?
TB9080FG implements motor overcurrent protection using the AMPP/AMPM/AMPO amplifier chain and ASHUT comparator input. An external shunt resistor senses motor current; the internal amplifier (gain set by Rmo/Rmg) conditions the signal, which is compared against a voltage divider on ASHUT. Exceeding the threshold triggers a 90% duty, 10 Hz pulse on DG and forces all pre-driver outputs low. The TB9080FG also supports peak current limiting via CLMT/LA.
Can TB9080FG operate in sleep mode, and how is it entered and exited?
Yes, TB9080FG supports sleep mode with 50 μA typical quiescent current. Sleep is entered when PSIG (Pin 1) remains high for ≥524 ms; this disables the 5 V main regulator (VREG), resets logic, and sets all pre-driver outputs low. Exit occurs on PSIG falling edge: VREG restarts, internal reset releases after ~8.2 ms, ASIG data is accepted, and PSIG operation resumes after two rising edges-unless PSIG period exceeds 131 ms, in which case ASIG mode persists.
What is the function of the DG pin on TB9080FG?
The DG (Pin 9) pin on TB9080FG is an open-drain diagnostic output that reports fault conditions via modulated pulse trains. Different faults produce distinct duty cycles and frequencies-for example, 30%/10 Hz for internal overtemperature, 90%/10 Hz for motor overcurrent, and 10%/10 Hz for motor lock or Hall sensor failure. The pulse width and repetition rate allow microcontrollers to decode fault type without additional analog monitoring circuitry.
Does TB9080FG support both PWM and analog speed control inputs?
Yes, TB9080FG supports dual-mode speed control: PSIG (Pin 1) accepts a PWM signal (7.6 Hz–1 kHz) where duty cycle sets target speed, and ASIG (Pin 5) accepts an analog voltage (0.4–0.6 V threshold) for linear speed setting. The IC automatically switches between modes-PSIG dominates above 7.6 Hz; below that, it defaults to ASIG. This flexibility allows compatibility with both microcontroller-based and analog-sensor-based vehicle ECUs.
