Product details

Overview

TMC6130-LA-T from TRINAMIC Motion Control GmbH & Co. KG is a 3-phase BLDC motor pre-driver IC designed to control six external N-channel MOSFETs in half-bridge configuration. It operates from 4.5 V to 28 V VM supply, integrates a high-bandwidth current sense amplifier (gain = ×17.2), supports 100% PWM operation via bootstrap and charge pump, and delivers diagnostic feedback via bidirectional ERROR pin. It enables precise torque control in compact battery-powered motion systems.

For engineers reviewing the TMC6130-LA-T datasheet, TMC6130-LA-T pinout, TMC6130-LA-T application, or TMC6130-LA-T equivalent, this page provides verified technical context, validated pin functions, confirmed operating ranges, real-world diagnostic behavior, and two rigorously cross-checked alternative pre-drivers for BLDC motor control designs requiring fast settling time, integrated EEPROM configuration, and fault-aware gate driving.

Technical Context

The TMC6130-LA-T implements a dual-path gate drive architecture: bootstrap circuits for high-side FETs (HS1–HS3) and direct low-side outputs (LS1–LS3), with configurable charge pump mode (CPMODE=0/1) to sustain gate voltage under low-V_M conditions. Its current sensing path uses differential inputs (RS+, RS−) feeding a programmable-gain amplifier (CUR output) referenced to VREF, enabling accurate shunt-based phase current measurement.

Diagnostics are implemented via a priority-encoded PWM ERROR signal (F_{ERROR_F} ≈ 100 kHz or F_{ERROR_S} ≈ 15.6 kHz), reporting 11 distinct fault conditions-including VDS overvoltage, VM over/undervoltage, overtemperature, and VCP_REG undervoltage-with hardware-enforced tri-state shutdown on VM_OV and configurable bridge feedback for VDS_ERR and VCP_REG_OV.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage (VM)	4.5 V to 28 V - defines minimum battery voltage for reliable operation and maximum DC bus rating before absolute max violation at 32 V.
Current Sense Gain	×17.2 - sets full-scale output swing of CURRENT pin for given shunt voltage; enables high-resolution torque feedback with low-noise settling.
ERROR PWM Frequency	100 kHz (fast mode) or 15.6 kHz (slow mode) - determines diagnostic update latency and microcontroller interrupt load during fault handling.
Sleep Current	<30 µA - achieved by pulling VCC to GND; disables all regulators and drivers while preserving EEPROM state for rapid wake-up.
Charge Pump Mode	Configurable (CPMODE=0 or 1) - selects whether VCP_REG is regulated relative to GND (default) or VM, affecting efficiency and thermal performance at low input voltage.
VDS Monitoring Threshold	2 V (default, adjustable via VDSMON[2:0]) - triggers overvoltage protection when drain-source voltage exceeds threshold, preventing FET avalanche failure.
Dead Time	1.0 µs (default, adjustable via DEAD_TIME[2:0]) - prevents shoot-through by enforcing minimum off-time between complementary HS/LS switching transitions.

Pinout & Package

Package: QFN-32, 5 mm × 5 mm, 0.5 mm pitch, exposed thermal pad (GNDP).

Pin/Terminal	Circuit Role	Design Meaning
RS+, RS−	Differential current sense inputs	Connect across shunt resistor; enable high-accuracy, low-drift phase current measurement with programmable gain.
CURRENT	Analog current sense output	Provides amplified shunt voltage; used for closed-loop torque control or diagnostic monitoring.
BH1–BH3, BL1–BL3	Digital PWM inputs	Accept microcontroller-generated PWM signals to configure high-side and low-side gate drive timing logic.
HS1–HS3, LS1–LS3	Gate drive outputs	Drive gates of external N-FETs; HS outputs use bootstrap or charge pump; LS outputs are direct low-side drivers.
ERROR	Bidirectional diagnostic interface	Transmits prioritized fault codes as PWM duty cycle; requires microcontroller acknowledgment to clear latches.
VCP1–VCP3, VCP_REG, VCP_SW	Charge pump supply network	Generate and regulate boosted gate drive voltage for high-side FETs; support operation down to 4.5 V VM.
VREF	Current sense reference	Sets common-mode level for shunt amplifier; typically derived from VCC via resistor divider for ratiometric accuracy.
ENABLE	Driver enable input	Active-high logic input; disables all gate outputs and enters Z-state when low; resets diagnostics on rising edge.

Key Features

Feature	Design Value
Integrated EEPROM	Pre-programmed default configuration (DEAD_TIME=1.0 µs, CUR_GAIN=×17.2, CPMODE=0) eliminates external resistors and simplifies BOM.
Fast-settling current sense	High GBW amplifier achieves fastest settling time in class with minimal noise-critical for high-bandwidth torque control loops.
Multi-level diagnostics	11 prioritized fault codes (VDS_ERR, OVT, VM_UV, etc.) delivered via ERROR pin with hardware tri-state shutdown on critical events like VM_OV.
Low-voltage gate drive	Charge pump + bootstrap architecture sustains >10 V gate drive for NFETs even at VM = 4.5 V, enabling wide battery voltage range.
Sleep mode quiescent current	<30 µA achieved by disabling VCC-supplied circuitry-extends runtime in portable and always-on motion systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar BLDC pre-driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN32F0B	Integrated 32-bit ARM Cortex-M0 MCU + gate drivers; no external EEPROM; single-package solution vs. TMC6130-LA-T's discrete pre-driver + external MCU architecture.	Best for space-constrained designs needing embedded motor control firmware; less flexible for custom algorithm porting than TMC6130-LA-T + external µC.	Select STSPIN32F0B when MCU integration reduces board area and BOM count; choose TMC6130-LA-T when full control over timing, diagnostics, and firmware independence is required.
MP6532	3-phase pre-driver with fixed 1.5 µs dead time, no EEPROM, no charge pump (requires external high-side supply), and no ERROR PWM diagnostics-only basic fault flags.	Suitable for cost-sensitive, non-safety-critical BLDC fans or blowers; lacks TMC6130-LA-T's diagnostic depth, low-voltage gate drive, and configurability.	Choose MP6532 for simple, high-volume fan drives; select TMC6130-LA-T when VDS monitoring, sleep mode <30 µA, or EEPROM-based tuning are mandatory.

Compared with STSPIN32F0B and MP6532, the TMC6130-LA-T uniquely combines EEPROM-based configuration, charge-pump-enabled low-voltage operation, and prioritized PWM diagnostics-making it optimal for battery-powered, safety-aware, and firmware-flexible BLDC systems where gate drive reliability and diagnostic transparency are design priorities.

FAQ

What is the absolute maximum VM voltage rating for the TMC6130-LA-T?

The TMC6130-LA-T has an absolute maximum VM rating of 32 V. Operation must remain within the functional range of 4.5 V to 28 V DC; exceeding 32 V risks permanent damage. The device includes hardware overvoltage protection that forces immediate tri-state shutdown if VM exceeds its safe threshold, independent of configuration settings.

How does the TMC6130-LA-T achieve gate drive at low VM voltages like 4.5 V?

The TMC6130-LA-T uses an integrated charge pump (VCP_REG) combined with bootstrap circuitry to generate sufficient gate-source voltage (>10 V) for external N-FETs even when VM = 4.5 V. In CPMODE=0 (default), VCP_REG is regulated relative to GND; in CPMODE=1, it tracks VM-enabling reliable high-side drive across the full 4.5–28 V operating range.

Can the TMC6130-LA-T operate without an external microcontroller?

No-the TMC6130-LA-T is a pre-driver IC and requires an external microcontroller to generate PWM signals (BHx/BLx), interpret ERROR diagnostics, and optionally reprogram EEPROM via SPI. It has no onboard motor control algorithm or processor; its role is strictly gate driving, current sensing, and fault management under MCU supervision.

What is the purpose of the VREF pin on the TMC6130-LA-T?

The VREF pin sets the common-mode reference voltage for the internal current sense amplifier. Applying a stable voltage (typically a resistor divider from VCC) to VREF defines the zero-current output level of the CURRENT pin and ensures ratiometric accuracy across temperature and supply variations-critical for repeatable torque control in the TMC6130-LA-T.

Does the TMC6130-LA-T support 100% duty cycle PWM operation?

Yes-the TMC6130-LA-T supports true 100% PWM operation using its integrated charge pump and bootstrap architecture. This avoids the gate voltage droop seen in conventional bootstrap-only drivers, enabling continuous conduction mode in BLDC applications without loss of high-side FET control-confirmed in the TMC6130-LA-T datasheet Section 3.2.
