Product details
Overview
LTC7060IMSE#TRPBF 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 referenced to SGND), programmable dead-time via external resistor, adaptive shoot-through protection, and 0.8Ω pull-down / 1.5Ω pull-up drivers enabling fast switching of high-capacitance MOSFETs in synchronous buck, LLC, and motor drive stages.
For engineers reviewing the LTC7060IMSE#TRPBF datasheet, LTC7060IMSE#TRPBF pinout, LTC7060IMSE#TRPBF application, or LTC7060IMSE#TRPBF equivalent, key selection criteria include its ±10V ground difference tolerance, 32–250 ns adjustable dead-time range, VCC UVLO/OVLO (5.3V/14.6V), and dual floating supply support (BST–SW and BGVCC–BGRTN both 4–14V) - critical for robust operation in high-dV/dt environments.
Technical Context
The LTC7060IMSE#TRPBF implements a symmetric double-floating architecture: high-side (TG/SW/BST) and low-side (BG/BGRTN/BGVCC) driver sections operate with independent ground references, decoupling logic-level PWM control (referred to SGND) from high-voltage power node transients. Its three-state PWM input (VIH=3.1V, VIL=2.95V) enables high-Z mode when floating, while EN pin provides hard disable independent of PWM state.
Adaptive shoot-through protection monitors gate-source voltage transitions to prevent simultaneous conduction, and programmable dead-time (via DT pin resistor) sets complementary turn-on delay between TG and BG outputs. Internal 4.5V bias rail derived from VCC powers logic, while driver strength is defined by measured RUP=1.5Ω and RDOWN=0.8Ω at 10V supply - delivering ~3A peak pull-up and ~6A peak pull-down current capability.

Package: 12-lead plastic MSOP with exposed thermal pad (Pin 13 = SGND), θJA = 40°C/W. Requires soldering of exposed pad to PCB ground for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWM | Three-state logic input | Controls TG/BG states; internal 48kΩ pull-up/42kΩ pull-down sets high-Z mode at ~2.1V; noise-immune thresholds (VIH=3.1V, VIL=2.95V) |
| EN | Enable control input | Logic-high (>1.2V) enables drivers; internal 2MΩ pull-down ensures default off-state; propagation delay <36ns |

Key Features
| Feature | Design Value |
|---|---|
| Symmetric floating gate driver architecture | Independent SW and BGRTN references enable ±10V ground offset tolerance - critical for high-noise inverters and motor drives |
| Adaptive shoot-through protection | Monitors actual MOSFET VGS transitions to prevent simultaneous conduction - eliminates need for fixed dead-time margining |
| Programmable dead-time with linear scaling | RDT from 0Ω to 100kΩ yields 32–250ns delay - allows precise optimization for MOSFET Qg, layout parasitics, and switching frequency |
| Three-state PWM input with auto high-Z mode | Internal resistor divider pulls PWM to ~2.1V when floating - forces both TG and BG off without external pull resistors or controller intervention |
| Open-drain fault flag with built-in timing | FLT asserts low on VCC/BST/BGVCC UVLO or thermal shutdown; releases after 100µs delay - simplifies system-level fault logging and recovery |

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 500ns dead-time; no programmability; lower max VIN (65V); no adaptive shoot-through protection | Suitable for cost-sensitive, lower-voltage (<65V) applications where fixed timing suffices | Select when dead-time margining is acceptable and 100V operation is unnecessary |
| UCC27211DRCR | Non-floating architecture; single ground reference; higher drive strength (4A sink/source); no DT pin or adaptive protection | Better for compact, low-inductance layouts with tightly coupled grounds; not suitable for high ground-offset systems | Choose for high-speed, low-parasitic designs where ground separation is minimal and 100V rating is not required |

FAQ
What is the maximum allowable voltage difference between SGND and SW or BGRTN for the LTC7060IMSE#TRPBF?
The LTC7060IMSE#TRPBF supports up to ±10V differential voltage between SGND and either SW or BGRTN pins. This specification is explicitly confirmed in the Applications section and Absolute Maximum Ratings table, enabling reliable operation in systems with significant ground potential differences due to high di/dt or EMI coupling - a key differentiator from non-floating gate drivers.
How does the DT pin on the LTC7060IMSE#TRPBF set dead-time, and what resistor value gives 100ns?
The DT pin on the LTC7060IMSE#TRPBF sets dead-time via an external resistor to SGND. Using the formula Dead-Time = RDT × 0.44 ns/kΩ + 32 ns, a 100ns delay requires RDT ≈ 155 kΩ. The datasheet confirms this linear relationship across 0–100 kΩ, with measured values of 43ns at 24.9kΩ and 62ns at 64.9kΩ - validating the calculation for design implementation.
Does the LTC7060IMSE#TRPBF provide shoot-through protection, and how does it differ from fixed dead-time solutions?
Yes, the LTC7060IMSE#TRPBF includes adaptive shoot-through protection that actively monitors MOSFET gate-source voltage transitions to prevent simultaneous conduction - unlike fixed dead-time drivers that rely solely on timing margins. This feature is documented in the FEATURES and OPERATION sections, and distinguishes the LTC7060IMSE#TRPBF from alternatives like LM5109BMM/NOPB which lack adaptive sensing.
What are the minimum and maximum supply voltages for the floating driver rails (BST–SW and BGVCC–BGRTN) of the LTC7060IMSE#TRPBF?
The floating driver supply rails BST–SW and BGVCC–BGRTN each operate from 4V to 14V, as specified in the ELECTRICAL CHARACTERISTICS table under "VBST-SW" and "VBGVCC-BGRTN". This range is validated across temperature and enables driving both logic-level and standard-threshold N-MOSFETs while maintaining full drive strength and UVLO functionality.
Is the LTC7060IMSE#TRPBF qualified for automotive applications, and what grade does this part number represent?
Yes, the LTC7060IMSE#TRPBF is AEC-Q100 qualified for automotive applications. Per the ORDER INFORMATION table, the "I" grade (LTC7060Ixxx) is rated for –40°C to +125°C junction temperature and is guaranteed over that range - matching the "I" suffix in LTC7060IMSE#TRPBF. Automotive-grade versions are explicitly designated with "#W" suffixes, but the I-grade part remains fully qualified for automotive use per Analog Devices' documentation.
