Product details

Overview

TLE6280GPAUMA2 from Infineon Technologies is a 3-phase bridge driver IC designed to control six external N-channel MOSFETs in high-current automotive motor drives. It delivers 0.9 A turn-on and 0.85 A turn-off gate drive current per channel, operates from 8–20 V supply, supports PWM up to 30 kHz, and integrates bootstrap diodes, adjustable dead time (100 ns–4 µs), and dI/dt limitation for EMI reduction - deployed in electric power steering and cooling fan modules.

For engineers reviewing the TLE6280GPAUMA2 datasheet, TLE6280GPAUMA2 pinout, TLE6280GPAUMA2 application, or TLE6280GPAUMA2 equivalent, key selection criteria include bootstrap-capable high-side drive with separate source connections, short-circuit protection via V_DS monitoring, shoot-through prevention with MFP-configurable override, and AEC-Q100 qualification for 12 V automotive systems.

Technical Context

The TLE6280GPAUMA2 implements three independent floating high-side and low-side gate drivers, each with dedicated source (SHx/SLx), gate (GHx/GLx), and bootstrap (BHx/BLx) terminals - enabling precise V_GS control even at >200 A phase current. Its integrated charge pump (CL/CH pins) sustains ≥13 V gate drive down to 9 V battery input, ensuring low R_DS(on) under cold-crank conditions.

Protection logic includes real-time V_DS-based short-circuit detection (threshold set by MFP voltage), thermal overload warning, undervoltage flag on individual bootstrap rails, and hardware-enforced shoot-through blocking - all signaled via open-drain ERR pin. Dead time is resistor-programmed (DT pin), while dI/dt regulation uses external high-pass feedback to DIDT pin for Miller-plateau-controlled slew rate limiting.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	8–20 V - supports full functionality including 13 V internal gate drive during 9 V cold-crank automotive operation
Gate Drive Current	0.9 A (on), 0.85 A (off) - sufficient to switch 250 nC MOSFETs with ~300 ns rise/fall times
Operating Temperature	−40 °C to +150 °C - qualified per AEC-Q100 Grade 0 for under-hood motor control
PWM Frequency Support	Up to 30 kHz - limited by bootstrap refresh timing and power dissipation at higher frequencies
Dead Time Adjustment	100 ns to 4 µs via external resistor on DT pin - balances shoot-through avoidance vs. conduction loss
Short-Circuit Response	~11 µs shutdown after V_DS threshold exceeded - gate voltage clamped to 2×V_MFP before full shutdown
dI/dt Control Input	DIDT pin accepts high-pass filtered transient voltage (±2–5 V) to dynamically slow switching only in Miller region

Pinout & Package

Package: PG-DSO-36 (36-pin exposed pad SOIC), RoHS-compliant, thermally enhanced for automotive motor drive PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
GND (Pins 1,18,19–36)	Logic Ground Reference	Common return for all digital inputs, error flag, and internal regulators - requires low-inductance connection to PCB ground plane
V_S (Pin 8)	Main Supply Input	8–20 V battery rail input; powers internal regulators and charge pump - decoupled via CVS and RVS per datasheet Fig. 1
IH1–IH3 (Pins 9,11,13)	High-Side Control Inputs	Active-low TTL-compatible signals controlling GH1–GH3 outputs - synchronized with ILx to trigger charge pump
IL1–IL3 (Pins 10,12,14)	Low-Side Control Inputs	Active-high TTL-compatible signals controlling GL1–GL3 outputs - initiate bootstrap capacitor recharge cycle
MFP (Pin 15)	Multi-Function Pin	Configures device disable (V<1.1 V), short-circuit threshold/gate clamp (2.5–4.0 V), or shoot-through disable (>4.5 V)
DT (Pin 17)	Dead Time Programming	Resistor-to-GND sets dead time between complementary HS/LS switching - critical for preventing cross-conduction
DIDT (Pin 35)	dI/dt Feedback Input	Accepts high-pass filtered V_DS transients to reduce gate drive strength only during Miller plateau - suppresses voltage spikes
VDH (Pin 34)	High-Side Drain Sense	Monitors V_DS of all three high-side MOSFETs for short-circuit detection - connected to drain nodes via RC filter
ERR (Pin 16)	Error Flag Output	Open-drain signal pulled low on short circuit, overtemperature, or bootstrap undervoltage - requires external 5 V pull-up
BH1–BH3 / BL1–BL3 (Pins 2,28,22 / 5,31,25)	Bootstrap Supplies	Provide floating 13 V gate drive for HS MOSFETs (BHx) and bias for LS stages (BLx) - require external 220 nF capacitors
GH1–GH3 / GL1–GL3 (Pins 3,29,23 / 6,32,26)	Gate Drive Outputs	Push-pull outputs driving MOSFET gates directly - rated for 0.9 A sink/source with fast edge rates
SH1–SH3 / SL1–SL3 (Pins 4,30,24 / 7,33,27)	Source Return Terminals	Dedicated source connections per half-bridge - enable Kelvin sensing and eliminate common-source inductance effects

Key Features

Feature	Design Value
Integrated Bootstrap Diodes	Eliminates need for 6 external bootstrap diodes - reduces BOM count and layout area in 3-phase inverter designs
Charge Pump with ILx Triggering	Self-synchronizing charge pump (CL/CH) activated by low-side turn-on - aligns refresh pulses with switching events to minimize EMI
Programmable dI/dt Limitation	DIDT pin enables dynamic, transient-triggered gate current reduction - suppresses V_DS overshoot without compromising steady-state efficiency
Hardware Shoot-Through Protection	Combinational logic blocks simultaneous IHx/ILx assertion per phase - prevents destructive cross-conduction even with faulty MCU firmware
AEC-Q100 Qualified	Validated for automotive Grade 0 (−40 °C to +150 °C) - meets stress test requirements for power steering and HVAC actuators

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
BD63002AMUV	Lacks integrated bootstrap diodes; requires external diodes and separate charge pump; lower max gate current (0.6 A)	Targeted at industrial BLDC drives with less stringent cold-crank requirements	Select when cost-sensitive industrial design allows added external components and reduced peak current demand
UCC27282D	6-channel high-side/low-side driver without integrated protection logic; no V_DS monitoring or ERR flag	Used in non-automotive, high-frequency (>100 kHz) SMPS or servo inverters with external fault management	Select when system-level MCU handles diagnostics and thermal management, and higher switching frequency is required

Compared with BD63002AMUV and UCC27282D, the TLE6280GPAUMA2 uniquely combines AEC-Q100 qualification, hardware-enforced shoot-through blocking, and bootstrap-regulated gate drive - making it the only choice for safety-critical 12 V automotive motor control where system-level fault handling cannot be assumed.

FAQ

What is the minimum battery voltage at which TLE6280GPAUMA2 maintains full gate drive capability?

The TLE6280GPAUMA2 sustains ≥13 V gate drive output down to 9 V battery input using its integrated charge pump and voltage regulator. Below 8 V, gate voltage decreases linearly with supply; operation below 6 V is not functional. This ensures reliable MOSFET enhancement during automotive cold-crank events.

How does the shoot-through protection interact with the MFP pin configuration?

When MFP voltage is 2.5–4.0 V, shoot-through protection is active and blocks simultaneous IHx/ILx assertion per phase. At MFP > 4.5 V, the protection is disabled - allowing forced simultaneous high/low-side turn-on for fuse-blow shutdown. At MFP < 1.1 V, the entire device is disabled and all outputs go low.

Can TLE6280GPAUMA2 drive MOSFETs with gate charge exceeding 250 nC?

Yes - the datasheet confirms it can drive MOSFETs up to 250 nC with ~300 ns switching times, or two parallel MOSFETs per channel (total 500 nC) with ~600 ns times. For higher gate charges, external gate resistors must be adjusted to manage power dissipation and ensure bootstrap capacitor recharge.

What external components are mandatory for basic operation?

Mandatory components include: one 1.5 µF charge pump capacitor (CCP) between CL and CH; three 220 nF bootstrap capacitors (CBH1–CBH3) between BHx and SHx; three 220 nF low-side bypass capacitors (CBL1–CBL3) between BLx and SLx; and decoupling capacitor CVS (1 µF) at VS. The DT and DIDT resistors are optional but recommended for tuning.
