Product details

Overview

TLE7183QUXUMA4 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 levels (SCD2/SCD5 available). It drives external N-channel MOSFETs in cooling fans, water pumps, and electric power steering systems.

For engineers reviewing the TLE7183QUXUMA4 datasheet, TLE7183QUXUMA4 pinout, TLE7183QUXUMA4 application, or TLE7183QUXUMA4 equivalent, key selection criteria include gate drive strength (400 nC MOSFET support), dead-time control (programmable via DT pin), short-circuit detection threshold (0.75 V or 2.0 V options), and AEC-Q100 qualification for under-hood environments.

Technical Context

The TLE7183QUXUMA4 integrates dual charge pumps (CH1/CL1 and CH2/CL2) to sustain high-side gate drive above VS during low-battery conditions (≥5.5 V), with level-shifted floating drivers for each half-bridge. Its diagnostic logic implements 2-bit error encoding on ERR1/ERR2 pins for short circuit, overtemperature, undervoltage, overvoltage, and overcurrent events.

Phase voltage feedback (U_fb/V_fb/W_fb) provides digital logic-level representations of motor phase voltages for commutation timing; shunt signal conditioning (ISP/ISN/VO) delivers amplified current-sense output with programmable overcurrent threshold (VTHOC) and bias reference (VRI/VRO) for precise motor current monitoring.

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	Single-supply 12 V operation only; no charge pumps; max 20 kHz PWM; no phase voltage feedback outputs	Lacks low-voltage operation and diagnostic granularity - suitable only for non-critical 12 V fans with stable supply	Select when cost sensitivity outweighs AEC-Q100 compliance and wide-VS operation
MPQ6535-AEC1	Integrated MOSFETs (60 V/3.5 A); no external shunt interface; only basic fault flag (not encoded)	Not pin-compatible; limited current capability; no VTHOC or DT programming - targets low-power auxiliary pumps	Choose for space-constrained designs where integration > flexibility and diagnostics

Compared with BD9M500MUV and MPQ6535-AEC1, the TLE7183QUXUMA4 uniquely combines wide-input operation (5.5–45 V), programmable protection thresholds, and full diagnostic encoding - making it the only option qualified for ASIL-B motor control in demanding under-hood environments.

FAQ

What is the function of the DT pin on the TLE7183QUXUMA4?

The DT (Dead Time) pin accepts an external resistor to set the minimum off-time between complementary high-side and low-side gate drive signals. This prevents shoot-through current by enforcing a programmable blanking interval (typically 100–500 ns), which is critical for reliable inverter operation with discrete MOSFETs.

How does the TLE7183QUXUMA4 support low-battery operation below 12 V?

The IC uses two integrated charge pumps (CH1/CL1 and CH2/CL2) to generate boosted gate-drive voltages for high-side MOSFETs, enabling full functionality down to 5.5 V supply. This ensures uninterrupted motor control during automotive cold-crank conditions without external boost circuitry.

Can the TLE7183QUXUMA4 drive both N-channel and P-channel high-side MOSFETs?

No - the TLE7183QUXUMA4 is designed exclusively for N-channel high-side MOSFETs, using floating high-side drivers with integrated level shifters and charge pumps. It does not support P-channel devices, which require different gate biasing and lack the necessary source-referenced sensing architecture.

What diagnostic information is conveyed by the ERR1 and ERR2 pins?

ERR1 and ERR2 are open-drain outputs that deliver a 2-bit binary code (00–11) indicating fault type: short circuit, overtemperature, undervoltage, overvoltage, or overcurrent. The encoding is defined in the datasheet Table 13 and requires no external decoding logic, simplifying ASIL-B-compliant system design.
