Product details

Overview

TLE6281GXUMA1 from Infineon Technologies is a dual-channel high- and low-side H-bridge gate driver IC for N-channel MOSFET power stages in brushed DC motor control. It delivers 850 mA turn-on and 580 mA turn-off peak gate current per channel, supports PWM frequencies up to 50 kHz, operates from 7.5 V to 60 V supply, and integrates adjustable dead time (10 ns–3.1 µs), short-circuit detection per switch, and thermal warning at 170 °C typical. It is used in 12 V/24 V/42 V automotive motor bridges requiring robust fault protection.

For engineers reviewing the TLE6281GXUMA1 datasheet, TLE6281GXUMA1 pinout, TLE6281GXUMA1 application, or TLE6281GXUMA1 equivalent, key selection considerations include bootstrap-compatible floating HS/LS drive capability, TTL-level PWM/DIR interface, independent SCD per channel, undervoltage lockout on both VS and BHx, and diagnostic ER1/ER2 flag differentiation between overtemperature and undervoltage events.

Technical Context

The TLE6281GXUMA1 implements two independent floating half-bridge drivers with integrated bootstrap diodes, level-shifted high-side outputs (GH1/GH2), and ground-referenced low-side outputs (GL1/GL2). Each channel features dedicated short-circuit sense pins (DH1/DH2) and source connections (SH1/SH2, SL1/SL2) enabling direct V_DS-based fault detection at 0.45–1.05 V thresholds.

It uses a programmable DT/DIS pin to configure dead time via external resistor (1 kΩ–200 kΩ), reset diagnosis registers, or force full output disable. The INH pin enables hardware sleep mode with quiescent current as low as 0.6 mA at 14 V, while dual open-drain ER1 (shutdown) and ER2 (warning) pins provide distinguishable fault reporting without microcontroller polling overhead.

Key Specifications

14 BH1, 17 BH2	Bootstrap supply inputs	Accept charge from external bootstrap capacitors; UVLO triggers at 3.7 V to prevent weak HS drive
15 DH1, 16 DH2	Short-circuit sense inputs	Monitor V_DS of HS MOSFETs; internal comparator trips at 0.45–1.05 V to initiate shutdown

Key Features

Feature	Design Value
PWM–DIR interface	Separate TTL-compatible inputs eliminate need for external direction logic; simplifies MCU GPIO usage
Adjustable dead time with shoot-through protection	Resistor-programmable delay prevents simultaneous HS/LS conduction-reduces body-diode conduction loss
Dual diagnostic flags (ER1/ER2)	ER1 indicates hard shutdown; ER2 distinguishes overtemperature (170 °C) from UVLO/SCD events-enables targeted recovery
Integrated bootstrap diodes	Eliminates need for external diodes in BHx paths-reduces BOM count and PCB area in compact motor modules
Inhibit mode with sub-1 mA quiescent current	INH pin pulls device into deep sleep; draws only 0.6 mA at 14 V-critical for always-on automotive ECU power budgets

Applications

Industrial Brushed DC Actuator

Use Scenario: Bidirectional lifting/lowering of vehicle windows using 12 V DC motors with stall detection and anti-pinch logic.

IC Role / Device Role / Timing Role: Dual H-bridge gate driver providing synchronized HS/LS switching, real-time short-circuit detection on each MOSFET, and thermal warning before motor stall overheats wiring.

Use Value: Prevents fuse blowing during jam events by triggering ER1 shutdown within 12 µs of V_DS rise, while ER2 allows firmware to log whether fault was thermal or electrical.

Use Scenario: Precision positioning of HVAC dampers or robotic joints using 24 V brushed motors with position feedback.

IC Role / Device Role / Timing Role: Gate driver enabling 20–50 kHz PWM for smooth torque control; DT/DIS pin dynamically adjusts dead time during acceleration/deceleration phases.

Use Value: Adjustable dead time minimizes cross-conduction losses across speed range, improving efficiency by ≥8% versus fixed-dead-time drivers at partial load.

42 V Mild Hybrid Starter Generator Interface

Off-Highway Equipment Motor Control

Use Scenario: Driving starter-generator bidirectional power flow in 42 V stop-start systems with regenerative braking capability.

IC Role / Device Role / Timing Role: High-voltage tolerant gate driver supporting 60 V transients; BHx pins rated to 90 V ensure reliable bootstrap operation during load dump.

Use Scenario: Controlling hydraulic pump motors in construction equipment exposed to −40 °C cold starts and dust-contaminated enclosures.

IC Role / Device Role / Timing Role: Robust gate driver operating from −40 °C to +150 °C junction; SL/SH pins tolerate −2 V reverse bias during inductive kickback.

Use Value: Guaranteed operation at −40 °C ensures immediate motor response during cold engine cranking-no preheat delay required.

Equivalent & Alternatives

The following parts are listed as comparable options for similar H-bridge gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS716G	Single-channel, no adjustable dead time; lower peak current (600 mA); no ER2 warning flag	Lacks dual-channel independence and thermal warning-requires external logic for multi-motor coordination	Select when cost-sensitive single-motor control suffices and diagnostics can be centralized
LM5109B	Non-automotive grade; no integrated bootstrap diodes; no short-circuit detection; wider temp range (−55 °C)	Requires external bootstrap diodes and discrete SCD circuit-increases design complexity and footprint	Select for non-automotive industrial use where AEC-Q100 compliance is not required

Compared with BTS716G and LM5109B, the TLE6281GXUMA1 provides integrated dual-channel drive with programmable timing, on-chip fault discrimination, and automotive-grade protection-reducing system-level BOM count by ≥7 components and eliminating external SCD analog front-end design.

FAQ

What is the minimum recommended bootstrap capacitor value for TLE6281GXUMA1 at 20 kHz PWM?

The datasheet specifies a 47 nF capacitor (CD) in the example circuit with 20 kHz operation. For reliable charge replenishment across temperature and load, a minimum 100 nF X7R ceramic capacitor rated ≥25 V is recommended-ensuring <5% droop on BHx during worst-case duty cycle and junction temperature.

How does the TLE6281GXUMA1 differentiate overtemperature warning from shutdown?

ER2 asserts low at 170 °C typical to warn of thermal overload; ER1 remains high. If junction exceeds 190 °C, ER1 pulls low and all outputs disable. This two-level signaling allows firmware to initiate fan activation or reduce PWM duty before shutdown occurs.

Can the DT/DIS pin be left unconnected, and what is its default state?

No-DT/DIS must be externally pulled to a defined voltage. Internal 20 µA pull-down sets it low by default, configuring minimum dead time (~10 ns). Leaving it floating risks erratic dead time and unintended register reset or disable pulses due to noise coupling.

Does TLE6281GXUMA1 support 3.3 V logic inputs for PWM and DIR?

Yes-its TTL-compatible inputs accept 0–5.5 V logic levels. A 3.3 V MCU output meets the 2.0 V minimum high-level threshold (V_IN(HL)) with 170 mV hysteresis, ensuring noise-immune switching even with rail-to-rail digital outputs.
