Product details
Overview
TLE7183FXUMA9 from Infineon Technologies is a 3-phase high- and low-side MOSFET gate driver IC for automotive motor control, featuring six independent gate outputs (GH1–GH3, GL1–GL3), 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 high-current inverters for electric power steering and cooling fans.
For engineers reviewing the TLE7183FXUMA9 datasheet, TLE7183FXUMA9 pinout, TLE7183FXUMA9 application, or TLE7183FXUMA9 equivalent, key selection criteria include its 48-pin VQFN package with exposed thermal slug, TTL-compatible inputs, 150 ns typical rise/fall times, shoot-through protection, and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE7183FXUMA9 integrates three floating high-side drivers with level shifters and three low-side drivers in a single monolithic IC, each pair supporting independent PWM control with programmable dead time via DT pin. Its dual charge pump architecture (CH1/CL1 and CH2/CL2) sustains gate drive capability at VS as low as 5.5 V.
It embeds real-time diagnostics including overcurrent warning (via VTHOC threshold setting), overtemperature warning, undervoltage/overvoltage shutdown, and dedicated ERR1/ERR2 fault reporting pins. Phase voltage feedback (U_fb/V_fb/W_fb) enables closed-loop commutation in BLDC motor systems.

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 |
|---|---|---|---|
| DRV3205-Q1 (TI) | Single-package 6-channel driver with integrated current sense ADC; no external VTHOC threshold setting; uses SPI for fault reporting instead of ERR pins | Lacks analog phase feedback (U_fb/V_fb/W_fb); requires MCU with SPI interface and higher software overhead for diagnostics | Prefer when digital diagnostics and integrated ADC reduce BOM count, but avoid if sensorless commutation using logic-level phase feedback is required |
| BD63002MUV (ROHM) | 48-pin QFN with similar gate drive strength; only one charge pump; no dedicated phase feedback inputs; supports only 3.3 V logic inputs | Not AEC-Q100 qualified; lacks U_fb/V_fb/W_fb interface; limited to 3.3 V MCU control, not 5 V tolerant | Select only for non-automotive industrial BLDC drives where AEC qualification and 5 V logic compatibility are unnecessary |
Compared with DRV3205-Q1 and BD63002MUV, the TLE7183FXUMA9 uniquely combines AEC-Q100 Grade 0 rating, logic-level phase feedback for sensorless commutation, analog VTHOC threshold selection, and dual charge pumps-making it optimal for cost-sensitive, high-reliability automotive inverter designs without MCU SPI dependency.

FAQ
What is the function of the VTHOC pin on the TLE7183FXUMA9?
The VTHOC pin sets the overcurrent detection threshold for short-circuit protection. Its voltage level-determined by internal resistor divider and factory-trimmed per SCD variant (SCD1–SCD5)-defines the current limit at which the driver triggers fault reporting via ERR1/ERR2. It is not user-adjustable in-circuit and must match the selected part number's fixed threshold.
Does the TLE7183FXUMA9 support 3.3 V logic inputs?
No. The TLE7183FXUMA9 accepts TTL-compatible logic inputs (IHx, ILx, ENAx, INH) with VIH = 2.0 V min and VIL = 0.8 V max, fully compatible with both 3.3 V and 5 V microcontrollers. Input voltage tolerance extends to 6.0 V, allowing direct interfacing without level-shifting circuitry.
How does the TLE7183FXUMA9 handle shoot-through prevention?
Shoot-through is prevented by integrated hardware-level dead time insertion between complementary high- and low-side gate outputs. The DT pin accepts an external resistor to set minimum off-time (typically 100–500 ns), enforced independently per phase. This logic-level timing control operates regardless of MCU timing jitter or software latency.
Can the TLE7183FXUMA9 drive P-channel high-side MOSFETs?
No. The TLE7183FXUMA9 is designed exclusively for N-channel high-side MOSFETs, using floating driver stages with integrated charge pumps to generate gate-source voltage above VS. Its GHx outputs are source-followers referenced to SHx, making them incompatible with P-channel devices requiring negative gate drive relative to source.
