Product details

Overview

VBG15NB22T5TR-E from STMicroelectronics is an automotive-grade high-voltage ignition coil driver IC using Powermesh™ technology, designed for precise coil current limiting (17–25 A typ.) and clamped voltage protection (225–275 V) in gasoline engine ignition systems. It integrates soft switch-off timing via external capacitor, internal overvoltage/overtemperature protection, and ESD immunity (2000 V HBM), eliminating need for external current-sense or clamp components.

For engineers reviewing the VBG15NB22T5TR-E datasheet, VBG15NB22T5TR-E pinout, VBG15NB22T5TR-E application, or VBG15NB22T5TR-E equivalent, key selection criteria include clamped VCE rating, integrated current limit accuracy, thermal resistance (1 °C/W junction-to-case), ISO 7637-2 transient immunity, and PowerSO-10 package thermal performance in under-hood environments.

Technical Context

The device implements a monolithic N-channel vertical power MOSFET with integrated bipolar driver and analog timer block. Its functional architecture combines a high-side switch with built-in current-limiting sense resistor (RSENSE), voltage clamp circuitry, and a capacitor-controlled soft turn-off ramp generator that linearly reduces coil current via transconductance amplifier feedback.

It operates as a single-ended, ground-referenced ignition driver with VIN control input, VCC supply (5.2–24 V), and HVC high-voltage collector output. Protection features include overtemperature shutdown, avalanche energy rating (250 mJ), and ISO 7637-2 pulse immunity up to Class IV (±100 V, 400 ms), meeting AEC-Q100 requirements for under-hood deployment.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CL Clamp Voltage	250 V typical at I_C = 15 A - ensures reliable spark generation while protecting against inductive kickback beyond 225–275 V range
I_CL Current Limit	21 A typical - internally set, temperature-stable coil current regulation without external sensing resistor
V_CE(sat)	2.2 V at I_C = 10 A, V_BAT = 6 V - low conduction loss enabling >95% efficiency in 12 V automotive systems
E_off Turn-off Loss	7.5 mJ at T_case = 25 °C - minimized by soft-switching timer, reducing thermal stress during repeated firing cycles
R_thj-case	1 °C/W maximum - enables 125 W continuous dissipation at 25 °C case temperature, critical for compact engine bay mounting
ESD Rating	2000 V HBM - inherent protection eliminates need for external TVS on control pins in harsh automotive environments
ISO 7637-2 Immunity	Class IV compliant - withstands ±100 V load-dump pulses (400 ms, 2 Ω) and ±150 V transients (0.1 µs, 50 Ω) without latch-up or damage

Pinout & Package

VBG15NB22T5TR-E is housed in a thermally enhanced PowerSO-10 surface-mount package with exposed die pad for direct PCB heat sinking. The 10-pin layout supports high-current routing and robust mechanical anchoring in vibration-prone engine compartments.

Pin/Terminal	Circuit Role	Design Meaning
1 (HVC)	High-Voltage Collector Output	Connects directly to ignition coil primary winding; rated for 250 V clamped operation and 21 A continuous current
2 (GND)	Power Ground	Common return for internal current sense, timer, and driver circuits; must be low-inductance connection to minimize noise coupling
3 (VIN)	Logic Input Control	CMOS-compatible enable signal (3 V threshold); controls switching with soft-start/soft-stop timing function
4 (VCC)	Supply Voltage Input	5.2–24 V DC supply; includes integrated transient protection per ISO 7637-2 Class IV
5 (STILL)	Soft-Off Timing Capacitor Node	Connects external 100 nF capacitor to set t_still delay (1–3 ms) for controlled current decay and reduced EMI
6–10 (Exposed Pad)	Thermal & Electrical Ground	Electrically tied to pin 2 (GND); provides primary thermal path to PCB copper area for 125 W dissipation capability

Key Features

Feature	Design Value
Integrated Coil Current Limit	21 A typical with ±10% stability over -40 to +150 °C - eliminates external shunt and amplifier, reducing BOM count and layout area
Programmable Soft Switch-Off	t_still adjustable from 1–3 ms via external C_still - reduces dI/dt-induced EMI and mechanical stress on ignition coil windings
High-Voltage Clamping	250 V clamped V_CE with 250 mJ avalanche energy rating - sustains repeated spark events without degradation or failure
AEC-Q100 Qualified	Automotive Grade 0 (-40 to +175 °C junction) - validated for under-hood use in gasoline direct injection and distributorless ignition systems
PowerSO-10 Thermal Performance	R_thj-case = 1 °C/W - enables full 125 W power handling with minimal heatsink requirement when mounted on ≥200 mm² 2-oz copper

Equivalent & Alternatives

The following parts are listed as comparable options for similar ignition driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STGD3HF60L	600 V, 3 A discrete IGBT with separate gate driver - requires external current sense, clamp, and timing circuitry	Lacks integrated current limit and soft-off; used in legacy designs where discrete flexibility is prioritized over integration	Select only if custom timing or multi-level current profiling is required; adds 7+ passive components and increases layout complexity
INFINEON BTS7163G	40 V, 30 A high-side switch with integrated diagnostics - no HV clamp or ignition-specific timing block	Designed for generic load driving (fuel pumps, fans); not rated for 250 V inductive flyback or AEC-Q100 ignition validation	Not suitable for ignition coil driving; use only for low-voltage auxiliary loads in same ECU chassis

Compared with STGD3HF60L and BTS7163G, VBG15NB22T5TR-E uniquely delivers complete ignition functionality - including clamp, current limit, soft-off, and ISO immunity - in a single AEC-Q100-qualified package, reducing total solution size by 45% and eliminating 12+ external components.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The VBG15NB22T5TR-E is rated for continuous operation at junction temperatures from -40 °C to +175 °C, as validated per AEC-Q100 Grade 0. Its R_thj-case of 1 °C/W enables full 125 W dissipation at 25 °C case temperature, but sustained operation above 150 °C requires active thermal monitoring and derating per Figure 5 in the datasheet.

Can the STILL pin be left unconnected or tied to ground?

No - the STILL pin must be connected to a 100 nF capacitor (±10%) referenced to GND to enable the soft switch-off function. Leaving it open disables timing control, resulting in hard turn-off, increased EMI, and potential coil insulation stress. Grounding it forces immediate turn-off and disables current ramp-down entirely.

Does this device support PWM-based dwell time control?

No - dwell time is fixed by the external STILL capacitor value and internal reference voltage; the device does not accept variable-frequency or duty-cycle-modulated inputs for dwell adjustment. Dwell is set once per design (1–3 ms range) and remains constant across operating conditions.

Is the PowerSO-10 package lead-free and RoHS-compliant?

Yes - the VBG15NB22T5TR-E carries ECOPACK® certification, confirming lead-free terminations and full compliance with RoHS Directive 2011/65/EU. The PowerSO-10 package uses matte tin plating over copper leadframe and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for standard SMT assembly.
