Product details
Overview
LTC7060IMSE#PBF from Analog Devices is a 100V half-bridge gate driver IC for dual N-channel MOSFETs in high-noise industrial and automotive power converters, featuring 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.
For engineers reviewing the LTC7060IMSE#PBF datasheet, LTC7060IMSE#PBF pinout, LTC7060IMSE#PBF application, or LTC7060IMSE#PBF equivalent, this page delivers verified technical context on symmetric floating architecture, three-state PWM input thresholds, VCC/BGVCC/BST UVLO/OVLO behavior, thermal shutdown at ~180°C, and MSOP-12 package layout constraints for high-voltage half-bridge designs.
Technical Context
The LTC7060IMSE#PBF implements a dual floating-level-shifter architecture: high-side driver referenced to BST/SW and low-side driver referenced to BGVCC/BGRTN, enabling ±10V ground differential tolerance between input (SGND) and output grounds. Its internal logic enforces strict sequencing via adaptive shoot-through protection and DT-pin-programmable propagation delay between complementary outputs.
Three-state PWM input uses fixed VIH(TG)=3.1V/VIL(TG)=2.95V and VIH(BG)=1.0V/VIL(BG)=1.25V thresholds with hysteresis to define high-Z, TG-on, and BG-on states-enabling DCM control without external logic. EN pin (1.2V threshold) provides synchronous disable with 2MΩ internal pull-down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Input Voltage | 100V VIN independent of VCC; supports wide-input DC/DC and telecom supplies |
| VCC Operating Range | 6V to 14V; powers internal bias circuitry and generates 4.5V reference for logic |
| Driver Supply Range | 4V to 14V per floating rail (BST-SW and BGVCC-BGRTN); drives logic- or standard-threshold MOSFETs |
| Pull-Down Resistance | 0.8Ω typical (TG & BG); delivers >6A peak sink current at 10V supply for fast turn-off |
| Pull-Up Resistance | 1.5Ω typical (TG & BG); delivers ~3A peak source current at 10V supply for controlled turn-on |
| Dead-Time Range | 32 ns (RDT = 0Ω) to 250 ns (RDT open); set by single resistor from DT to SGND |
| UVLO Thresholds | VCC: 5.3V (falling), BGVCC/BST: 3.4V (falling); prevents erratic switching during brownout |
Pinout & Package
Package: 12-lead plastic MSOP (MSE) with exposed thermal pad (Pin 13 = SGND), θJA = 40°C/W, rated for –40°C to 125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWM | Three-state logic input | Defines TG/BG state via voltage thresholds; floating = high-Z (both off); requires minimized trace capacitance |
| EN | Enable control input | Logic-high (>1.2V) enables drivers; internal 2MΩ pull-down ensures default disable |

Key Features
| Feature | Design Value |
|---|---|
| Symmetric floating architecture | Independent SW and BGRTN references enable ±10V ground differential tolerance and noise immunity in high-dv/dt environments |
| Adaptive shoot-through protection | Monitors external MOSFET VGS transitions to prevent simultaneous conduction-no external timing components needed |
| Three-state PWM interface | Fixed VIH/VIL thresholds with hysteresis allow controller-driven high-Z mode for DCM, eliminating need for external gate logic |
| Programmable dead-time | Single RDT resistor sets identical BG→TG and TG→BG delays (32–250 ns), simplifying layout vs dual-resistor schemes |
| Triple UVLO monitoring | Independent lockout for VCC, BGVCC-BGRTN, and BST-SW ensures safe operation even if one floating supply collapses |

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 DT pin adjustment; lower max VIN (65V); no adaptive shoot-through protection | Suitable for cost-sensitive, lower-voltage (<65V) industrial SMPS where programmable dead-time is not required | Select when design prioritizes simplicity over flexibility and operates below 65V input |
| UCC27211DRCR | Non-floating architecture (single ground); higher drive strength (4A source/4A sink); no UVLO on floating rails | Better for low-noise, single-ground systems like server VRMs; unsuitable for high dv/dt or ground-isolated topologies | Choose for high-current, low-voltage (<20V) synchronous buck where ground separation is unnecessary |

FAQ
What is the maximum input voltage rating for the LTC7060IMSE#PBF?
The LTC7060IMSE#PBF supports up to 100V on the VIN node (SW and BGRTN pins), independent of the VCC supply voltage. This allows direct integration into high-input-voltage DC/DC converters without level-shifting circuitry. Absolute maximum ratings specify –10V to 100V for SW and BGRTN relative to SGND, with BST and BGVCC rated to 115V.
How does the three-state PWM input function on the LTC7060IMSE#PBF?
The LTC7060IMSE#PBF PWM pin interprets three voltage states: >3.1V enables TG-on, <1.0V enables BG-on, and 1.9–2.3V (floating) forces high-Z mode where both TG and BG are turned off. Internal 48kΩ pull-up and 42kΩ pull-down resistors create a defined threshold window, enabling Discontinuous Conduction Mode (DCM) control directly from a microcontroller GPIO without external logic.
What is the purpose of the DT pin on the LTC7060IMSE#PBF?
The DT pin on the LTC7060IMSE#PBF programs the dead-time between complementary TG and BG transitions using a single resistor to SGND. It sets identical propagation delays for BG→TG and TG→BG edges-from 32 ns (0Ω) to 250 ns (open). This eliminates shoot-through risk in high-voltage half-bridges and enables optimization for specific MOSFET gate charge and switching frequency.
Does the LTC7060IMSE#PBF include protection features beyond UVLO?
Yes, the LTC7060IMSE#PBF integrates adaptive shoot-through protection that monitors external MOSFET VGS to prevent simultaneous conduction, thermal shutdown at ~180°C (resumes at 165°C), and open-drain FLT pin reporting all faults-including VCC UVLO/OVLO, BGVCC-BGRTN UVLO, BST-SW UVLO, and overtemperature-with 100µs release delay after fault clearance.
Is the LTC7060IMSE#PBF qualified for automotive applications?
Yes, the LTC7060IMSE#PBF is AEC-Q100 qualified for automotive applications (Grade I: –40°C to +125°C junction temperature). It meets stringent reliability, ESD, and transient immunity requirements for under-hood and battery-management systems, and its symmetric floating architecture provides inherent noise immunity critical for automotive 48V/12V DC/DC converters.
