Product details
Overview
LTC7060IMSE#WTRPBF from Analog Devices is a 100V half-bridge gate driver IC for dual N-channel MOSFETs in high-noise industrial and automotive power converters. It features independent floating grounds (SW and BGRTN), 0.8Ω pull-down / 1.5Ω pull-up drivers, programmable dead-time via external resistor, adaptive shoot-through protection, and operates with VCC from 6V to 14V - enabling robust control of high-voltage synchronous buck, LLC, and motor drive half-bridges.
For engineers reviewing the LTC7060IMSE#WTRPBF datasheet, LTC7060IMSE#WTRPBF pinout, LTC7060IMSE#WTRPBF application, or LTC7060IMSE#WTRPBF equivalent, this page delivers verified technical context, exact pin functions, confirmed thermal and electrical specs per AEC-Q100 Grade I (–40°C to 125°C), and real-world alternative selection guidance - all grounded in Analog Devices' Rev. B datasheet and official parametric data.
Technical Context
The LTC7060IMSE#WTRPBF implements a symmetric double-floating architecture: high-side driver (TG/BST/SW) and low-side driver (BG/BGVCC/BGRTN) each reference independent ground domains, tolerating ±10V ground difference versus SGND. Its three-state PWM input uses fixed VIH/VIL thresholds (e.g., VIH(TG) = 3.1V typ, VIL(BG) = 1.25V typ) with internal 48kΩ pull-up and 42kΩ pull-down to enable high-Z off-state without external logic.
Shoot-through prevention combines adaptive gate monitoring with programmable dead-time (32ns to 250ns via RDT), while UVLO/OVLO protection acts independently on VCC (5.3V/14.6V thresholds), BST–SW (3.4V UVLO), and BGVCC–BGRTN (3.4V UVLO). The exposed-pad 12-lead MSOP package achieves θJA = 40°C/W and supports AEC-Q100 qualification for automotive underhood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Max | 100V - Enables direct use in 48V, 60V, and 80V bus systems without level-shifting or auxiliary supplies. |
| VCC Range | 6V to 14V - Powers internal logic and generates 4.5V bias rail; compatible with standard 12V system rails. |
| RDOWN(TG/BG) | 0.8Ω typ - Delivers >6A peak sink current at 10V supply, ensuring fast MOSFET turn-off and cross-conduction immunity. |
| RUP(TG/BG) | 1.5Ω typ - Supplies ~3A peak source current at 10V, supporting rapid turn-on of high-QG MOSFETs. |
| Dead-Time Range | 32ns to 250ns - Set by single RDT (0Ω to open); prevents shoot-through in hard-switched and resonant topologies. |
| Operating Temp | –40°C to 125°C - Qualified per AEC-Q100 Grade I; validated for automotive engine control and industrial SMPS. |
| Package | 12-Lead Plastic MSOP with exposed SGND pad - Provides low thermal resistance (θJA = 40°C/W) and EMI-suppressing ground plane integration. |
Pinout & Package
12-lead plastic MSOP package with exposed pad (Pin 13 = SGND), requiring soldering to PCB ground for thermal and electrical performance. Pin pitch: 0.5mm; body dimensions: 3mm × 3mm × 1.1mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWM | Three-state logic input | Drives TG/BG complementary; floating state forces both outputs low; internal 48kΩ pull-up/42kΩ pull-down enable HIZ mode without external components. |
| EN | Enable control input | Logic-high (>1.2V) enables drivers; internal 2MΩ pull-down ensures safe default-off state during MCU boot or fault. |
| FLT | Open-drain fault flag | Pulls low on VCC UVLO/OVLO, floating supply UVLO, or thermal shutdown; 60Ω typical RDS(ON) supports direct LED or microcontroller interrupt interface. |
| DT | Dead-time programming | Resistor-to-SGND sets identical BG→TG and TG→BG propagation delay (32–250ns); no trimming required. |
| VCC | IC bias supply | Supplies internal 4.5V regulator; bypass with ≥0.1µF ceramic capacitor to SGND; independent of VIN and floating supplies. |
| BGVCC / BGRTN | Low-side floating supply rails | BGVCC–BGRTN powers BG output (4–14V range); Kelvin connection of BGRTN to MOSFET source ensures noise-immune gate drive. |
| BST / SW | High-side floating supply rails | BST–SW powers TG output (4–14V); SW must be Kelvin-connected to high-side MOSFET source for transient rejection. |
| TG / BG | Gate driver outputs | Drive N-MOSFET gates directly; 0.8Ω/1.5Ω RDS(ON) enables <18ns rise/fall into 3.3nF load - critical for >1MHz switching. |
| NC | No internal connection | Physically present but unconnected; must remain floating to isolate adjacent HV pins (BST, SW, BG). |
| SGND | Chip ground reference | Primary ground for VCC, EN, PWM, DT, FLT; exposed pad (Pin 13) must be soldered to PCB ground plane for thermal and EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetric floating gate architecture | Independent SW and BGRTN references tolerate ±10V ground offset vs SGND - eliminates ground-loop-induced false triggering in noisy 48V+ systems. |
| Adaptive shoot-through protection | Monitors actual MOSFET VGS states to enforce sequencing - prevents simultaneous conduction even during fast dV/dt transients or layout parasitics. |
| Programmable dead-time with single resistor | RDT sets matched delays for both BG→TG and TG→BG transitions (32–250ns), removing need for matched RC networks or digital controllers. |
| Three-state PWM with auto-HIZ | Internal resistor divider pulls PWM to 2.1V when floating - guarantees safe off-state without MCU GPIO or external pull resistors. |
| AEC-Q100 qualified Grade I | Validated for –40°C to 125°C operation with full parametric testing - meets automotive powertrain and ADAS subsystem reliability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5109BMM/NOPB | Fixed 120ns dead-time; no programmability; lower max VIN (65V); no floating ground tolerance (±2V only). | Suitable for cost-sensitive 24V/48V industrial SMPS where ground noise is controlled and dead-time margin is sufficient. | Select LM5109BMM/NOPB only if VIN ≤ 65V, ground offsets < ±2V, and fixed dead-time meets timing budget - avoids LTC7060IMSE#WTRPBF's AEC-Q100 and floating-ground advantages. |
| UCC27211DRCR | Non-isolated, single-ground architecture; 120V abs max; no adaptive shoot-through; requires external dead-time circuitry. | Fits high-voltage AC-DC PFC stages where shared ground is acceptable and external timing control is already implemented. | Choose UCC27211DRCR when board space is constrained and floating grounds are unnecessary - but expect added design effort for shoot-through mitigation and noise filtering. |
Compared with LM5109BMM/NOPB and UCC27211DRCR, the LTC7060IMSE#WTRPBF uniquely delivers programmable dead-time, ±10V floating ground tolerance, and AEC-Q100 qualification - making it the only option for automotive 48V systems and industrial converters subject to severe ground noise.

FAQ
What is the maximum input voltage rating for the LTC7060IMSE#WTRPBF?
The LTC7060IMSE#WTRPBF supports up to 100V maximum input voltage (VIN) across SW and BGRTN pins, with absolute maximum ratings of 115V for BST and BGVCC relative to their respective return pins. This allows direct use in 48V, 60V, and 80V bus architectures without external voltage clamping or level-shifting circuitry - a key differentiator from 65V-class alternatives like the LM5109B.
How does the LTC7060IMSE#WTRPBF achieve noise immunity between control and power grounds?
The LTC7060IMSE#WTRPBF achieves noise immunity through its symmetric double-floating architecture: the SW pin (high-side return) and BGRTN pin (low-side return) each operate independently of SGND, tolerating up to ±10V ground potential difference. This eliminates ground-loop coupling in high-dV/dt environments - confirmed by test data showing stable operation under 10Vpp common-mode noise on SW/BGRTN versus SGND.
Can the LTC7060IMSE#WTRPBF drive both logic-level and standard-threshold MOSFETs?
Yes - the LTC7060IMSE#WTRPBF supports gate driver supply voltages from 4V to 14V on both BST–SW and BGVCC–BGRTN rails, enabling compatibility with logic-level MOSFETs (requiring ≥4.5V VGS) and standard-threshold devices (requiring ≥10V VGS). Its 0.8Ω pull-down and 1.5Ω pull-up drivers deliver >6A sink and ~3A source current at 10V, ensuring robust turn-on/turn-off across this range.
What is the purpose of the NC pin on the LTC7060IMSE#WTRPBF?
The NC (No Connection) pin on the LTC7060IMSE#WTRPBF is intentionally unconnected internally and serves solely as a physical spacer between high-voltage pins (BST and SW). It must remain floating - connecting it risks compromising creepage/clearance or inducing parasitic coupling. Its presence maintains safe isolation in the 12-lead MSOP package, especially critical in 100V applications.
Does the LTC7060IMSE#WTRPBF include thermal shutdown protection?
Yes - the LTC7060IMSE#WTRPBF incorporates junction temperature sensing with thermal shutdown activation at approximately 180°C. When triggered, TG is pulled to SW and BG is pulled to BGRTN, forcing both MOSFETs off. Operation resumes automatically once junction temperature falls below 165°C. This feature is production-guaranteed for the –40°C to 125°C operating range and complements its 150°C maximum rated junction temperature.
