Product details
Overview
TLE7183QUXUMB1 from Infineon 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, and fixed short-circuit detection thresholds (SCD1–SCD5). It drives external N-channel MOSFETs in cooling fans, electric power steering, and water pumps.
For engineers reviewing the TLE7183QUXUMB1 datasheet, TLE7183QUXUMB1 pinout, TLE7183QUXUMB1 application, or TLE7183QUXUMB1 equivalent, key selection criteria include gate drive strength (400 nC load, ~150 ns rise/fall), dual enable inputs (ENA1/ENA2), phase voltage feedback (U_fb/V_fb/W_fb), shunt-based current sensing (ISP/ISN/VO), and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE7183QUXUMB1 integrates three floating high-side drivers with level-shifted logic and three ground-referenced low-side drivers, each with dedicated input (IHx/ILx) and output (GHx/GLx) pins. It employs two independent charge pump circuits (CH1/CL1/CB1 and CH2/CL2/CB2) to sustain high-side gate voltage above VS during 100% duty cycle operation.
Protection architecture includes per-phase short-circuit detection referenced to VDH, shoot-through prevention via programmable dead time (DT pin), undervoltage/overvoltage shutdown, overtemperature warning, and 2-bit error coding on ERR1/ERR2 pins. Phase voltage feedback (U_fb/V_fb/W_fb) provides digital logic-level representations of motor phase potentials.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5 V to 45 V - supports cold-crank operation (down to 5.5 V) and load-dump transients (up to 45 V). |
| Max PWM Frequency | 30 kHz - enables high-resolution motor torque control without audible noise in automotive cabin environments. |
| Gate Drive Capability | Drives 400 nC MOSFET gates with ~150 ns rise/fall times - ensures fast switching and reduced conduction losses in high-current inverters. |
| Short-Circuit Detection | 5 fixed SCD levels (0.5 V to 2.0 V at VDH) - configurable per application for precise fault thresholding in varied motor winding resistances. |
| Operating Junction Temp | −40 °C to +150 °C - qualified per AEC-Q100 Grade 0, enabling placement near power stages in engine bay modules. |
| Shunt Amplifier Gain | Fixed gain current sense amplifier (ISP/ISN → VO) - provides isolated, rail-to-rail output for analog current monitoring without external op-amps. |

Pinout & Package
Package: PG-TQFP-48 with exposed heat slug - thermally enhanced 7 mm × 7 mm footprint optimized for automotive PCB layouts requiring high power dissipation and EMI robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SH1–SH3 | High-side source reference | Connects to drain of external high-side MOSFETs; used as return path for VDH-based short-circuit detection. |
| GH1–GH3, GL1–GL3 | Gate drive outputs | Direct high-current outputs (±1 A peak) driving MOSFET gates; GHx floats with HS topology, GLx referenced to GND. |
| IH1–IH3, IL1–IL3 | Control inputs | Separated active-low (IHx) and active-high (ILx) logic inputs - enable independent PWM control of each half-bridge leg. |
| U_fb, V_fb, W_fb | Phase voltage feedback | Digital logic outputs indicating high/low state of motor phases - eliminates need for external comparators in sensorless FOC implementations. |
| ISP / ISN / VO | Current sense interface | Differential shunt input (ISP/ISN) with buffered single-ended output (VO) - supports Kelvin-connected current sense resistors for accurate motor phase current measurement. |
| DT | Dead time programming | Analog pin setting minimum off-time between complementary HS/LS switching - prevents shoot-through in hardware without MCU intervention. |
| ERR1 / ERR2 | Error status encoding | 2-bit coded outputs reporting fault type (short circuit, overtemp, UVLO, OVLO) - reduces diagnostic pin count vs. discrete fault flags. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pumps | Two independent charge pump circuits (CH1/CL1/CB1 and CH2/CL2/CB2) sustain high-side gate drive at VS ≥ 5.5 V - eliminates need for external bootstrap diodes/capacitors. |
| Sleep mode | Ultra-low quiescent current (<10 µA) with ENA1/ENA2 inactive - meets automotive "off" current budgets for always-on modules. |
| Programmable dead time | Analog DT pin sets minimum interlock delay (adjustable via resistor) - ensures robust shoot-through protection across temperature and process variation. |
| 2-bit error diagnosis | ERR1/ERR2 encode five fault types (SC, OT, UV, OV, OC) in binary - simplifies fault decoding with only two MCU GPIOs instead of five dedicated lines. |
| AEC-Q100 qualified | Grade 0 (−40 °C to +150 °C) qualification - validated for under-hood placement in EPS, HVAC, and transmission control units without derating. |

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-LB | Single-supply 3-phase driver (no charge pumps); max VS = 28 V; no VDH-based short-circuit detection. | Limited to 12 V systems without load dump; lacks integrated SCD and phase feedback outputs. | Choose for cost-sensitive, non-AEC-Q100 interior modules where 5.5–28 V range suffices and external fault logic is acceptable. |
| MP6543GQ-P | Integrated 3-phase MOSFET driver + gate drivers only; no current sense amplifier or phase feedback outputs; max VS = 30 V. | No shunt signal conditioning or U_fb/V_fb/W_fb logic outputs - requires external ADC/comparator for current/voltage monitoring. | Prefer when board space is constrained and system-level diagnostics are handled externally; not suitable for AEC-Q100 Grade 0 deployment. |
Compared with BD9M500MUV-LB and MP6543GQ-P, the TLE7183QUXUMB1 uniquely combines AEC-Q100 Grade 0 qualification, dual charge pumps for 5.5 V operation, VDH-referenced SCD, and integrated phase feedback - making it the only option qualified for direct replacement in safety-critical, high-voltage automotive inverter designs.

FAQ
What is the purpose of the VDH pin?
The VDH pin serves as the reference node for short-circuit detection across all three high-side switches. It connects to the common drain node of the external high-side MOSFETs and compares sensed voltage against five factory-set thresholds (SCD1–SCD5). This enables fast, localized fault detection without relying on current-sense amplifiers or microcontroller polling.
Can TLE7183QUXUMB1 operate without external charge pump capacitors?
No. The TLE7183QUXUMB1 requires two external charge pump capacitor networks: CH1/CL1/CB1 for high-side driver 1 and CH2/CL2/CB2 for drivers 2 and 3. Omitting these capacitors disables high-side gate drive functionality, resulting in incomplete 3-phase operation and potential shoot-through risk during commutation.
How does the DT pin affect dead time configuration?
The DT pin accepts an external resistor to set minimum dead time between complementary high-side and low-side gate signals. Resistance values from 10 kΩ to 100 kΩ yield dead times from ~200 ns to ~2 µs. This hardware-programmed interlock ensures deterministic shoot-through protection independent of MCU firmware timing jitter or interrupt latency.
Is TLE7183QUXUMB1 compatible with 48 V mild-hybrid systems?
No. The absolute maximum supply voltage is 45 V (with 10 Ω + 1 µF clamp), and functional operation is specified up to 40 V. While it withstands brief 45 V transients, sustained 48 V operation exceeds its rated functional range and risks permanent damage to internal charge pumps and level shifters.
