Product details

Overview

LTC7060EMSE#WPBF from Analog Devices is a 100V half-bridge gate driver IC designed to control dual N-channel MOSFETs in high-noise, high-voltage power stages. It features independent floating grounds for high-side (BST/SW) and low-side (BGVCC/BGRTN) drivers, 0.8Ω pull-down / 1.5Ω pull-up drive strength, programmable dead-time via external resistor, and adaptive shoot-through protection. It is used in automotive-grade isolated DC/DC converters and telecom half-bridge power supplies.

For engineers reviewing the LTC7060EMSE#WPBF datasheet, LTC7060EMSE#WPBF pinout, LTC7060EMSE#WPBF application, or LTC7060EMSE#WPBF equivalent, key selection criteria include its ±10V ground difference tolerance, AEC-Q100 qualification, 32–250 ns adjustable dead-time range, and dual floating supply architecture enabling robust operation in 100V bus systems with fast switching transients.

Technical Context

The LTC7060EMSE#WPBF implements a symmetric double-floating gate driver architecture: both high-side (TG/BST/SW) and low-side (BG/BGVCC/BGRTN) sections operate with independent ground references, decoupling logic-level PWM input (referred to SGND) from high-voltage power domains. This enables ±10V ground potential difference tolerance without signal corruption.

Its three-state PWM input supports high-impedance (Hi-Z) mode when floating, forcing both outputs off; combined with EN pin control and open-drain FLT fault flag, it supports Discontinuous Conduction Mode (DCM) and safe startup/shutdown sequencing. Adaptive shoot-through protection monitors gate-source voltage transitions to prevent simultaneous conduction, while programmable dead-time (via DT pin resistor) adds deterministic timing margin beyond adaptive logic.

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 floating ground tolerance (requires common GND); 60V max V_HS; no AEC-Q100 rating.	Lower-cost solution for non-automotive 48V systems where ground noise <1V and shoot-through risk is mitigated by layout.	Select only if ±10V ground offset immunity and automotive qualification are not required; verify layout isolation meets LM5109B's common-ground constraint.
UCC27211DRCR	60V max V_DD; no programmable dead-time; 1.8Ω/1.3Ω drive strength; no adaptive shoot-through; no AEC-Q100 grade.	Suitable for cost-sensitive industrial SMPS with tight board space; lacks floating domain architecture for high-noise environments.	Choose when budget limits dominate and system ground integrity is tightly controlled; avoid in automotive or telecom where transient immunity is critical.

Compared with LM5109BMM/NOPB and UCC27211DRCR, the LTC7060EMSE#WPBF uniquely combines AEC-Q100 qualification, ±10V floating ground tolerance, and resistor-programmable dead-time-making it the only option among the three qualified for automotive 48V systems requiring robust noise immunity and precise timing control.

FAQ

What is the maximum allowable voltage difference between SGND and BGRTN or SW in the LTC7060EMSE#WPBF?

The LTC7060EMSE#WPBF supports a voltage difference of –10V to +100V between SGND and BGRTN, and between SGND and SW. This ±10V ground offset tolerance enables operation in electrically noisy environments-such as automotive 48V systems-where chassis and power ground potentials diverge significantly during transients. The LTC7060EMSE#WPBF maintains correct logic interpretation and driver functionality across this full range without external level-shifting circuitry.

How does the LTC7060EMSE#WPBF implement adaptive shoot-through protection?

The LTC7060EMSE#WPBF monitors actual gate-source voltage transitions of the external MOSFETs-not fixed timing-to determine when it is safe to enable the opposite-side driver. It prevents the low-side MOSFET from turning on until the high-side MOSFET's V_GS falls below its threshold, and vice versa. This real-time sensing eliminates unnecessary dead-time while guaranteeing shoot-through immunity, unlike fixed-delay drivers. The LTC7060EMSE#WPBF achieves this without external sensors or feedback paths.

Can the LTC7060EMSE#WPBF drive logic-level MOSFETs?

Yes, the LTC7060EMSE#WPBF supports gate driver supply voltages from 4V to 14V on both BST–SW and BGVCC–BGRTN rails, making it compatible with logic-level N-channel MOSFETs requiring V_GS = 4.5V–5V. Its 0.8Ω pull-down and 1.5Ω pull-up strengths deliver sufficient peak current (e.g., >6A sink at 10V) to rapidly charge/discharge logic-level gate capacitances. However, drive strength decreases at lower supply voltages, so design validation at minimum 4V is recommended for critical timing margins.

What is the function of the NC pin on the LTC7060EMSE#WPBF?

The NC (No Connection) pin on the LTC7060EMSE#WPBF is intentionally unconnected internally and must remain floating-never tied to any voltage or ground. It is physically placed between high-voltage pins (SW and BG) to increase creepage and clearance distances, improving isolation and reducing risk of arcing in high-voltage PCB layouts. Soldering or routing to the NC pin violates the device's safety and reliability specifications and may cause field failure.

Is an external bootstrap diode required for the LTC7060EMSE#WPBF's high-side driver?

Yes, an external Schottky diode is required between V_CC (or another stable supply) and the BST pin to recharge the BST–SW bootstrap capacitor during each switching cycle. The LTC7060EMSE#WPBF does not contain an internal charging path; it only discharges the BST capacitor during high-side conduction. A low-forward-voltage, fast-recovery Schottky diode (e.g., 1N5819) minimizes voltage drop and ensures reliable high-side gate drive across temperature and load conditions. The LTC7060EMSE#WPBF datasheet specifies typical values and placement guidelines.
