Product details
Overview
LTC7060EMSE#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), programmable dead-time (32–250 ns), 0.8Ω pull-down / 1.5Ω pull-up drive strength, and adaptive shoot-through protection. It operates with VCC = 6–14V and supports gate driver supplies up to 14V referenced to SW or BGRTN.
For engineers reviewing the LTC7060EMSE#TRPBF datasheet, LTC7060EMSE#TRPBF pinout, LTC7060EMSE#TRPBF application, or LTC7060EMSE#TRPBF equivalent, key selection criteria include floating ground tolerance (±10V), symmetric dual-floating architecture, three-state PWM input with enable, open-drain fault flag, and AEC-Q100 qualification for automotive systems requiring robust gate drive under transient conditions.
Technical Context
The LTC7060EMSE#TRPBF implements a symmetric double-floating architecture: high-side driver (TG/BST/SW) and low-side driver (BG/BGVCC/BGRTN) operate with independent ground references, enabling ±10V ground differential immunity. Its level-shifting logic uses internal 4.5V bias derived from VCC, while UVLO/OVLO monitors VCC (5.3V/14.6V thresholds), BST–SW, and BGVCC–BGRTN (3.4V UVLO each).
Dead-time is precisely programmed via an external resistor on DT pin (32 ns min, 250 ns max), and adaptive shoot-through protection prevents simultaneous conduction by monitoring gate-source voltage transitions. The three-state PWM input includes internal 48 kΩ pull-up and 42 kΩ pull-down resistors, with defined VIH/VIL thresholds for TG and BG control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Input Voltage | 100V - Enables direct use in 48V, 60V, and 96V bus systems without external level shifting. |
| VCC Operating Range | 6V to 14V - Powers internal logic and generates 4.5V bias; compatible with standard 12V supply rails. |
| Driver Output RDS(ON) | 0.8Ω pull-down / 1.5Ω pull-up - Delivers >6A peak sink / ~3A peak source at 10V, driving large QG MOSFETs fast. |
| Dead-Time Range | 32 ns to 250 ns - Programmable via single RDT; ensures safe non-overlap in high-dV/dt half-bridge switching. |
| Floating Supply UVLO | 3.4V (BST–SW & BGVCC–BGRTN) - Prevents weak turn-on of MOSFETs during bootstrap capacitor discharge. |
| Operating Temp Range | –40°C to 125°C - Qualified per AEC-Q100 Grade E; suitable for under-hood automotive and industrial environments. |
| Package Thermal θJA | 40°C/W - Exposed pad (Pin 13 = SGND) must be soldered for rated thermal performance in continuous operation. |
Pinout & Package
Package: 12-lead plastic MSOP with exposed thermal pad (Pin 13 = SGND). Requires PCB soldering of exposed pad for electrical grounding and thermal dissipation (θJA = 40°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWM | Three-state logic input | Drives TG/BG complementary states; floats to High-Z (both off) when undriven; internal 48kΩ pull-up / 42kΩ pull-down. |
| EN | Enable control input | Logic-high (>1.2V) enables drivers; internal 2MΩ pull-down ensures default disable; overrides PWM state. |
| FLT | Open-drain fault output | Pulls low (60Ω typical) on VCC UVLO/OVLO, floating supply UVLO, or thermal shutdown; requires external pull-up. |
| DT | Dead-time programming | Resistor to SGND sets propagation delay (32–250 ns); linear relationship: Dead-Time = RDT × 0.44 ns/kΩ + 32 ns. |

| BGVCC | Bottom gate driver supply | 4–14V referenced to BGRTN; powers BG output stage; requires local ceramic capacitor to BGRTN. |
| BGRTN | Bottom driver return | Kelvin-connected to bottom MOSFET source; tolerates –10V to 100V vs SGND for noise immunity. |
| BG | Bottom gate driver output | Drives N-MOSFET gate between BGVCC and BGRTN; 0.8Ω pull-down / 1.5Ω pull-up; rise/fall time ≤18 ns @ 3.3nF. |
| BST | Top gate driver supply | 4–14V referenced to SW; powers TG output stage; requires local bootstrap capacitor to SW. |
| TG | Top gate driver output | Drives N-MOSFET gate between BST and SW; symmetric to BG; same drive strength and timing specs. |

| Adaptive shoot-through protection | Monitors actual MOSFET VGS transitions-not fixed timing-to prevent cross-conduction under varying load/temperature conditions. |
| Three-state PWM with enable | Enables DCM operation in synchronous buck converters; EN pin provides hardware-level override for fail-safe shutdown. |
| Programmable dead-time | Single-resistor adjustment (RDT) covers full range from 32 ns (hard-switching) to 250 ns (resonant/soft-switching) without firmware changes. |

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 100 ns dead-time; no floating ground tolerance (max ±2V); no three-state PWM; 105V abs max. | Lower-cost solution for non-automotive, lower-noise 48V systems where ground isolation is not critical. | Select LM5109BMM/NOPB only if ±10V ground differential immunity and programmable dead-time are unnecessary. |
| UCC27211DR | Non-isolated dual-driver (single ground); 120V abs max; no UVLO on floating supplies; no adaptive shoot-through. | Preferred for cost-sensitive industrial SMPS where layout allows tight ground coupling and bootstrap stability is assured. | Choose UCC27211DR when board space is constrained and floating supply monitoring is managed externally. |
Compared with LM5109BMM/NOPB and UCC27211DR, the LTC7060EMSE#TRPBF uniquely delivers symmetric floating grounds, programmable dead-time, and adaptive shoot-through-making it the only option qualified for AEC-Q100 automotive half-bridge systems requiring ±10V ground noise immunity and robust fault coverage.

FAQ
What is the maximum allowable ground voltage difference between SGND and BGRTN or SW for LTC7060EMSE#TRPBF?
The LTC7060EMSE#TRPBF supports up to ±10V ground potential difference between SGND and BGRTN, and between SGND and SW. This specification is explicitly guaranteed in the Absolute Maximum Ratings table and validated in the Applications section for high-noise immunity. Exceeding ±10V risks latch-up or permanent damage. Kelvin connections to MOSFET sources are mandatory to maintain this margin in real layouts.
How does the LTC7060EMSE#TRPBF implement adaptive shoot-through protection?
The LTC7060EMSE#TRPBF implements adaptive shoot-through protection by monitoring actual gate-source voltage transitions of the external MOSFETs-not fixed timing delays. It prevents the low-side MOSFET from turning on until the high-side MOSFET's VGS falls below its threshold, and vice versa. This dynamic response adapts to temperature, MOSFET variation, and load conditions-unlike fixed dead-time schemes-and is detailed in the Operation section under "Adaptive Shoot-Through Protection".
Can the LTC7060EMSE#TRPBF drive both logic-level and standard-threshold MOSFETs?
Yes, the LTC7060EMSE#TRPBF supports gate driver supply voltages from 4V to 14V (BST–SW and BGVCC–BGRTN), enabling compatibility with both logic-level (e.g., 4.5V VGS(th)) and standard-threshold (e.g., 10V VGS(th)) N-channel MOSFETs. The datasheet notes optimization for higher-threshold devices at 10V, but operation down to 4V is fully specified-including pull-up/pull-down resistance and rise/fall times-with derated drive current.
What is the function of the NC pin on the LTC7060EMSE#TRPBF, and how should it be handled?
The NC (No Connection) pin on the LTC7060EMSE#TRPBF is intentionally unconnected internally and serves to electrically isolate adjacent high-voltage pins (SW and BG). It must remain floating-never tied to SGND, VCC, or any other node-as stated in the Pin Functions section. PCB layout must avoid routing traces or copper near this pin to prevent parasitic coupling or voltage breakdown in high-dV/dt applications.
Does the LTC7060EMSE#TRPBF include thermal shutdown, and what are its trip and recovery thresholds?
Yes, the LTC7060EMSE#TRPBF includes thermal shutdown that activates at approximately 180°C junction temperature, pulling BG to BGRTN and TG to SW to disable both MOSFETs. Recovery occurs automatically when junction temperature cools below 165°C. This feature is documented in the "Protection Circuitry" section and is not production tested-but the device is guaranteed to operate continuously below 150°C junction temperature per its rated range.
