Product details
Overview
TLE6282GXUMA1 from Infineon Technologies is a dual half-bridge gate driver IC designed for high-current DC-brush motor control and automotive injector/valve applications. It supports independent operation of two half-bridges, delivers 850 mA turn-on and 580 mA turn-off gate drive current per channel, operates from 7.5 V to 60 V supply, and integrates bootstrap diodes, adjustable dead time (100 ns–3.1 µs), and short-circuit protection with configurable thresholds.
For engineers reviewing the TLE6282GXUMA1 datasheet, TLE6282GXUMA1 pinout, TLE6282GXUMA1 application in PWM-controlled motor bridges or injector drivers, or TLE6282GXUMA1 equivalent for AEC-Q100-compliant 12/24/42 V power net systems, this page provides verified functional context, validated pin roles, real-world protection behavior, and direct alternative comparisons.
Technical Context
The TLE6282GXUMA1 implements two fully isolated floating high-side and low-side drivers with independent bootstrap supplies (BH1/BH2), each supporting up to 50 kHz PWM switching. Its architecture includes integrated linear regulators, undervoltage lockout on both VS (4.8–5.9 V) and BHx (3.7–4.6 V), and differential short-circuit detection using DLx/DHx sense inputs referenced to GLx/GHx outputs.
Dead time is externally adjustable via resistor on DT/DIS pin (1 kΩ–200 kΩ), enabling precise shoot-through prevention or intentional overlap for valve pre-charge. The ERR open-collector flag reports combined fault conditions-short circuit, UVLO, or disable activation-with reset capability via controlled DT/DIS pulse width (3.1–3.4 µs).

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BD6841KV | Single-supply operation only (VS = 8–28 V); no bootstrap diodes; lower gate drive (±350 mA) | Limited to 12/24 V systems; requires external bootstrap diodes and higher gate resistance for same slew rate | Select when cost-sensitive 24 V-only designs prioritize simplicity over wide voltage range and integration |
| UCC27211D | Non-isolated dual low-side/high-side driver; no integrated SCP or UVLO; 4 A peak drive | Requires external fault monitoring, level-shifting, and protection circuitry; not AEC-Q100 qualified | Select for non-automotive, high-speed industrial SMPS where raw drive strength outweighs protection integration |
Compared with BD6841KV and UCC27211D, the TLE6282GXUMA1 uniquely combines AEC-Q100 qualification, integrated bootstrap diodes, dual-rail flexibility, and configurable SCP in a single PG-DSO-20 package - making it the only drop-in solution for automotive injector/valve modules requiring 7.5–60 V operation and diagnostic reporting.

FAQ
What is the purpose of the DT/DIS pin's three operating regions?
The DT/DIS pin serves three distinct functions: below 1.0 V disables dead time to allow simultaneous high- and low-side conduction for valve pre-charge; between 1.5 V and 3.5 V adjusts dead time from 100 ns to 3.1 µs via external resistor; above 4.0 V resets the ERR register (3.1–3.4 µs pulse) or disables all outputs (>7 µs pulse). This multi-function pin reduces external component count while preserving design flexibility.
How does short-circuit protection work on the TLE6282GXUMA1?
SCP uses differential VDS sensing: DHx/DLx pins monitor MOSFET source voltage relative to GHx/GLx outputs. When VDS exceeds 0.45 V (HS) or 0.5 V (LS) for ≥6 µs, the driver shuts down the affected channel and pulls ERR low. Thresholds and filter time can be adjusted via external resistors, and SCP can be disabled per channel for specific load types like inductive valves.
Can the TLE6282GXUMA1 drive high-side and low-side MOSFETs with different supply voltages?
Yes - the two half-bridges operate independently with separate VS connections. Each high-side driver uses its own BHx bootstrap supply referenced to its SHx node, enabling one bridge to run from 12 V while the other runs from 42 V. This allows co-integration of injector and auxiliary valve drivers in multi-rail automotive ECUs without level-shifting circuitry.
Is external bootstrap diode required when using the TLE6282GXUMA1?
No - the TLE6282GXUMA1 integrates bootstrap diodes internally (anode connected to VS, cathode to BH1/BH2). This eliminates external diodes, reduces board space, and improves reliability in high-vibration environments. External capacitors (e.g., 47 nF ceramic + 47 µF electrolytic) are still required on BHx pins to sustain gate drive during duty cycles >98%.
