Product details
Overview
TLE7183FXUMA2 from Infineon Technologies is a 3-phase high- and low-side MOSFET driver IC for automotive motor control, featuring six independent gate drivers (3 high-side + 3 low-side), integrated charge pumps enabling operation down to 5.5 V supply, 30 kHz PWM capability, short-circuit protection with five selectable detection thresholds, and shunt-based current sensing. It is used in electric power steering and water pump inverters.
For engineers reviewing the TLE7183FXUMA2 datasheet, TLE7183FXUMA2 pinout, TLE7183FXUMA2 application, or TLE7183FXUMA2 equivalent, key selection criteria include gate drive strength for 400 nC MOSFETs, dead-time programmability via DT pin, phase voltage feedback (U_fb/V_fb/W_fb), diagnostic ERR1/ERR2 outputs, and AEC-Q100 qualification for automotive 12 V systems.
Technical Context
The TLE7183FXUMA2 integrates three floating high-side drivers with level shifters and three low-side drivers, each with independent TTL-compatible inputs (IHx active-low, ILx active-high) and dedicated source/gate terminals (SHx/SLx, GHx/GLx). It uses dual charge pumps (CH1/CL1, CH2/CL2) to sustain high-side gate drive at VS ≥ 5.5 V.
Protection logic includes per-channel short-circuit detection referenced to VDH, overcurrent warning via ISP/ISN shunt amplifier, undervoltage/overvoltage shutdown, thermal warning, and hardware-enforced dead time with shoot-through prevention. Diagnostics are reported through ERR1 (global fault) and ERR2 (overtemperature/overcurrent warning).
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GH1–GH3, GL1–GL3 | High-/low-side gate drive outputs | Direct connection to MOSFET gates; GHx require floating level-shifting for high-side operation |

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 12 V operation only; no charge pumps; max VS = 28 V | Lacks cold-crank support and VDH-based short-circuit detection | Prefer for non-automotive 12 V industrial inverters where battery transients are absent |
| MPQ6532-AEC1 (Monolithic Power) | Integrated MOSFETs (60 V/10 A); no external gate drive flexibility; shunt amp not included | Not a driver IC - monolithic half-bridge; unsuitable for high-current discrete MOSFET designs | Select only when board space is constrained and current ≤10 A per phase |
Compared with BD9M500MUV-E2 and MPQ6532-AEC1, the TLE7183FXUMA2 uniquely supports 5.5–45 V operation with programmable short-circuit thresholds and discrete MOSFET scalability - essential for >30 A automotive traction inverters.

FAQ
What is the function of the VDH pin on the TLE7183FXUMA2?
The VDH pin connects to the drain nodes of all three high-side MOSFETs and serves as the reference point for short-circuit detection. When a phase-to-ground short occurs, the voltage at VDH collapses below a preset threshold, triggering ERR1 assertion. Its voltage rating varies with INH state (up to 55 V when INH=high), enabling direct connection without external resistive dividers.
How does the TLE7183FXUMA2 support low-voltage operation during cold cranking?
The device incorporates two independent charge pumps (CH1/CL1 and CH2/CL2) that generate boosted gate-drive voltages, sustaining high-side driver functionality even when VS drops to 5.5 V. This eliminates the need for external boost converters and ensures uninterrupted motor control during automotive battery dips below 6 V.
Can the TLE7183FXUMA2 drive both N-channel and P-channel high-side MOSFETs?
No - the TLE7183FXUMA2 is designed exclusively for N-channel high-side MOSFETs. Its floating high-side drivers use level-shifted logic and charge-pump-generated gate voltages to ensure VGS remains ≥10 V, which is incompatible with P-channel gate drive requirements (which need negative VGS relative to source).
What diagnostic signals does the TLE7183FXUMA2 provide, and how are they used?
The IC provides ERR1 (latched global fault) and ERR2 (warning flag) open-drain outputs. ERR1 asserts on short circuit, undervoltage, or overvoltage; ERR2 asserts on overtemperature or overcurrent warning. Both are intended for direct connection to microcontroller GPIOs with pull-up resistors, enabling real-time fault classification and safe shutdown sequencing without software polling.
