Product details
Overview
TLE7183FXUMA7 from Infineon Technologies is a 3-phase high- and low-side MOSFET gate driver IC for automotive motor control, featuring six independent gate outputs (3 high-side + 3 low-side), integrated charge pumps enabling operation down to 5.5 V supply, and fixed short-circuit detection with five selectable thresholds. It drives external N-channel MOSFETs in cooling fans, water pumps, and electric power steering systems.
For engineers reviewing the TLE7183FXUMA7 datasheet, TLE7183FXUMA7 pinout, TLE7183FXUMA7 application, or TLE7183FXUMA7 equivalent, key selection criteria include its VQFN-48 package with exposed thermal slug, TTL-compatible control inputs, 150 ns typical rise/fall times, shoot-through protection with programmable dead time, and AEC-Q100 qualification for automotive use.
Technical Context
The TLE7183FXUMA7 integrates three floating high-side drivers with integrated level shifters and bootstrap/charge-pump support (CH1/CL1/CB1 and CH2/CL2/CB2), enabling reliable high-side switching even at low battery voltages (down to 5.5 V). Each high-side output (GH1–GH3) and low-side output (GL1–GL3) is independently controlled via dedicated active-high (ILx) and active-low (IHx) inputs.
It embeds comprehensive protection: short-circuit detection on all six channels with five factory-set thresholds (via VTHOC pin), overcurrent warning via shunt amplifier (VO/ISP/ISN), undervoltage/overvoltage shutdown, overtemperature warning, and hardware-based dead-time insertion (DT pin) plus shoot-through prevention logic. Phase voltage feedback (U_fb/V_fb/W_fb) supports closed-loop motor commutation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BD9M500MUV-E2 (Rohm) | Single-supply 3-phase driver with integrated pre-driver only; no embedded charge pumps - requires external bootstrap circuitry for high-side operation. | Lacks AEC-Q100 Grade 0 rating and multi-threshold short-circuit detection; suited for non-safety-critical cabin fans. | Select when cost-sensitive designs tolerate external bootstrap components and relaxed thermal/safety requirements. |
| MPQ6530-AEC1 (Monolithic Power) | Integrated 3-phase inverter (60 V, 10 A) with embedded MOSFETs; no external FET support - monolithic vs. driver-only architecture. | Not pin-compatible; eliminates gate drive design but limits max current and thermal management flexibility. | Choose for space-constrained, lower-power (<500 W) applications where integration outweighs field-replaceability of power stage. |
Compared with BD9M500MUV-E2 and MPQ6530-AEC1, the TLE7183FXUMA7 uniquely combines AEC-Q100 Grade 0 qualification, dual charge pumps for true 5.5 V operation, and five-programmable short-circuit thresholds - making it the only option supporting high-current, safety-aware motor drives with field-serviceable external MOSFETs.

FAQ
What is the purpose of the VTHOC pin on the TLE7183FXUMA7?
The VTHOC pin selects one of five fixed short-circuit detection thresholds via an applied analog voltage. This allows designers to tune the current-limit trip point per motor phase without modifying external components-critical for balancing torque and fault tolerance across asymmetric windings in EPS or pump motors.
Does the TLE7183FXUMA7 require external bootstrap diodes for high-side driving?
No. The TLE7183FXUMA7 integrates two independent charge pump circuits (CH1/CL1/CB1 and CH2/CL2/CB2) that generate boosted gate drive voltage internally. This eliminates the need for external bootstrap diodes and capacitors, enabling reliable high-side operation even during cold-crank conditions down to 5.5 V supply voltage.
How does the TLE7183FXUMA7 handle shoot-through prevention?
The TLE7183FXUMA7 implements hardware-enforced dead time via the DT pin, which sets a minimum off-time between complementary high-side and low-side gate signals. Combined with internal shoot-through protection logic, this prevents simultaneous conduction in half-bridge legs-even during fast PWM transitions or input timing skew.
Can the TLE7183FXUMA7 be used with 24 V commercial vehicle systems?
Yes. Its absolute maximum supply voltage is 45 V with transient tolerance up to 47 V, and it operates fully functional from 5.5 V to 45 V. This range covers both 12 V passenger car and 24 V commercial vehicle battery systems-including load-dump transients-without external voltage clamping or regulation.
