Product details
Overview
TLE7183F from Infineon Technologies is a 3-phase high- and low-side MOSFET driver IC for automotive motor control, featuring six independent gate drivers (3 HS/3 LS), integrated charge pumps enabling operation down to 5.5 V supply, 30 kHz PWM capability, short-circuit protection with five fixed detection thresholds, and shunt-based current sensing. It drives external N-channel MOSFETs in electric power steering and water pump inverters.
For engineers reviewing the TLE7183F datasheet, TLE7183F pinout, TLE7183F application, or TLE7183F equivalent, key selection criteria include gate drive strength for 400 nC MOSFETs, dead-time programmability via DT pin, phase voltage feedback logic outputs (U_fb/V_fb/W_fb), and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE7183F integrates three floating high-side drivers with level-shifted control and three low-side drivers, each with dedicated input pins (IHx/ILx) and gate outputs (GHx/GLx). Its dual charge pump architecture (CH1/CL1 and CH2/CL2) sustains high-side gate drive at VS ≥ 5.5 V, while internal shoot-through protection enforces minimum dead time between complementary switch transitions.
Current sensing is implemented via a precision op-amp (VO/ISP/ISN) referenced to AGND, with overcurrent warning triggered by VTHOC threshold comparison. Phase voltage feedback uses digital comparators to generate U_fb/V_fb/W_fb logic signals indicating high/low state of each motor phase relative to mid-rail.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV3205-Q1 | Single-package 3-phase driver with integrated MOSFETs (40 V, 10 A); no external shunt amplifier or phase feedback outputs | Suitable for lower-power fans/pumps where integration outweighs diagnostic flexibility | Select when board space is constrained and peak current ≤ 10 A per phase |
| MC33883 | Legacy 3-phase driver with discrete charge pump design; lacks VQFN thermal performance and AEC-Q100 Grade 0 rating | Used in legacy chassis systems with less stringent thermal or safety requirements | Select only for backward compatibility in existing designs with validated thermal layout |
Compared with DRV3205-Q1 and MC33883, the TLE7183F offers superior thermal management via exposed-pad VQFN, configurable short-circuit thresholds, and dedicated phase feedback logic - making it optimal for new ASIL-B/C EPS and EWP designs requiring field-serviceable diagnostics.

FAQ
What is the purpose of the VTHOC pin on the TLE7183F?
The VTHOC pin sets the overcurrent detection threshold for the integrated current-sense amplifier. An external resistor between VTHOC and GND defines the trip point for overcurrent warning (OCW) - enabling system-specific current-limit tuning without modifying PCB layout or adding external comparators.
How does the TLE7183F support operation at low battery voltage?
The TLE7183F uses two integrated charge pumps (CH1/CL1 and CH2/CL2) to generate boosted gate-drive voltages for high-side MOSFETs, allowing full functionality down to VS = 5.5 V. This eliminates reliance on bootstrap capacitors and ensures reliable startup during cold-crank conditions.
Can the TLE7183F drive both N-channel and P-channel high-side MOSFETs?
No - the TLE7183F is designed exclusively for N-channel high-side MOSFETs. Its floating high-side drivers use level-shifted control and charge-pump voltage boosting, which are incompatible with P-channel gate drive requirements (negative VGS).
What diagnostic functions are reported through ERR1 and ERR2?
ERR1 reports latched faults including short circuit, overtemperature, and undervoltage shutdown. ERR2 provides pulsed warnings for overcurrent and overvoltage events. Both pins are open-drain and can be wire-OR'd to a single microcontroller interrupt input for consolidated fault handling.
