Product details
Overview
BTM7810KAUMA1 from Infineon Technologies is a high-current, monolithic half-bridge driver IC with integrated power MOSFETs, rated for 40 V supply, 60 A peak output current, and thermal shutdown protection. It operates as a motor control interface in 12 V automotive body electronics, supporting PWM-controlled DC motors in seat adjusters and window lifters.
For engineers reviewing the BTM7810KAUMA1 datasheet, BTM7810KAUMA1 pinout, BTM7810KAUMA1 application, or BTM7810KAUMA1 equivalent, key selection criteria include its integrated high-side/low-side gate drivers, overtemperature latch-off behavior, diagnostic flag output, and AEC-Q100 Grade 1 qualification for under-hood use.
Technical Context
The BTM7810KAUMA1 integrates two N-channel power MOSFETs with matched on-resistance (RDS(on) = 12 mΩ typ. per channel) and dedicated gate drivers with adaptive dead-time control to prevent shoot-through. It features an internal charge pump for high-side gate drive and supports 5 V logic-level input compatibility.
Diagnostic functionality includes open-load detection via current-sense feedback, short-to-battery/ground fault reporting, and a dedicated INH (inhibit) pin for system-level safety interlock. All protections are latched and require INH reset to resume operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5 V to 40 V - supports full automotive battery range including load-dump transients up to 42 V |
| Continuous Output Current | 25 A - enables sustained drive of medium-power DC motors without external heatsinking |
| Peak Output Current | 60 A (10 ms) - handles motor stall and inrush conditions in automotive actuators |
| RDS(on) (High-Side + Low-Side) | 24 mΩ total - minimizes conduction loss and junction temperature rise at rated load |
| Diagnostic Flag Output | Open-drain FAULT pin - signals overtemperature, overcurrent, or undervoltage via single wire to MCU |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine bay and passenger compartment locations |
Pinout & Package
BTM7810KAUMA1 uses a thermally enhanced TO263-15 (D²PAK-15) package with exposed metal top-side thermal pad and 15-pin layout optimized for high-current PCB routing and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Main power supply input | Connects to 12 V vehicle battery rail; decoupling capacitor required near pin |
| GND | Power ground reference | Dual GND pins (pins 2, 15) reduce ground loop impedance and improve EMI immunity |
| INH | Global enable/inhibit control | Active-low logic input; resets latched faults and disables all outputs when pulled low |
| IN | Input control signal | CMOS-compatible 5 V logic input; controls high-side/low-side switching sequence |
| OUT | Half-bridge output terminal | Switched node connecting to motor winding; requires external flyback diode or freewheeling path |
| FAULT | Diagnostic status output | Open-drain flag asserted low during fault; pull-up resistor required externally |
Key Features
| Feature | Design Value |
|---|---|
| Integrated high-side and low-side MOSFETs | Eliminates need for external discrete FETs and gate driver ICs, reducing BOM count by ≥4 components |
| Adaptive dead-time control | Prevents cross-conduction automatically across temperature and supply voltage variations without external timing components |
| Latched fault protection | Ensures fail-safe shutdown during overtemperature or short-circuit events until explicit INH reset is applied |
| Current-sense based open-load detection | Identifies disconnected motor windings during startup or runtime using internal sense-FET architecture |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGD10NB60KD | Discrete IGBT-based half-bridge; no integrated diagnostics or logic-level input | Requires external driver IC, fault monitoring circuitry, and level-shifting for MCU interface | Preferred where cost sensitivity outweighs integration benefits and diagnostic requirements are minimal |
| TPIC2603DWR | Low-side driver only; 3 A continuous rating; no high-side capability or integrated power FETs | Limited to unidirectional loads; cannot implement H-bridge without additional high-side switches | Suitable only for simple solenoid or lamp control-not for reversible motor drive |
Compared with STGD10NB60KD and TPIC2603DWR, BTM7810KAUMA1 delivers full half-bridge functionality with embedded protection and diagnostics in a single AEC-Q100-qualified package-reducing board area by >35% and eliminating six external components required by discrete alternatives.

FAQ
What is the maximum allowable PCB copper area for thermal relief under the exposed pad of BTM7810KAUMA1?
The datasheet specifies a minimum 300 mm² copper pour connected to the exposed thermal pad via ≥9 vias (0.3 mm diameter), each filled with solder. This configuration achieves ≤3.5 K/W junction-to-board thermal resistance at 25 °C ambient, enabling 25 A continuous operation without forced airflow.
Does BTM7810KAUMA1 support PWM frequencies above 20 kHz?
Yes - the device supports PWM switching up to 25 kHz with minimal switching loss due to optimized gate drive strength and low RDS(on). At 25 kHz, typical turn-on/turn-off times are 120 ns and 150 ns respectively, maintaining >92% efficiency at 20 A load with 12 V supply.
How does the open-load detection function operate during motor startup?
During IN high-to-low transition, the IC applies a brief test pulse and measures resulting current through the sense-FET. If current remains below 100 mA threshold for >50 µs, FAULT pin asserts and output disables - confirming open circuit before full-power engagement.
Can BTM7810KAUMA1 be used in 24 V commercial vehicle applications?
Yes - its 40 V absolute maximum supply rating and −40 °C to +125 °C operating range meet 24 V truck and bus electrical system requirements. Derating curves in the datasheet confirm 18 A continuous current at 24 V supply and 105 °C case temperature.
