Analog Devices Inc. LTC7062EMSE#TRPBF

Overview

LTC7062EMSE#TRPBF from Analog Devices is a 100V dual high-side N-channel MOSFET gate driver IC with independent floating supplies, 0.8Ω pull-down / 1.5Ω pull-up drive strength, TTL/CMOS-compatible inputs, and open-drain fault indicator - designed for high-noise industrial and automotive power converters operating up to 100V input.

For engineers reviewing the LTC7062EMSE#TRPBF datasheet, LTC7062EMSE#TRPBF pinout, LTC7062EMSE#TRPBF application, or LTC7062EMSE#TRPBF equivalent, key selection criteria include floating supply voltage range (4V–14V per channel), ±10V ground difference tolerance, thermal shutdown at ~180°C, VCC UVLO/OVLO thresholds (4.3V/14.6V), and 12-lead MSOP package with exposed pad for thermal management.

Technical Context

The LTC7062EMSE#TRPBF implements two fully symmetric, isolated high-side gate drivers-each with dedicated floating supply (G1VCC/G1RTN and G2VCC/G2RTN) referenced to its own return node, enabling operation across ±10V ground potential differences. Its level-shifting logic accepts TTL/CMOS inputs and drives outputs between respective floating rails with 1.5Ω pull-up and 0.8Ω pull-down resistance.

Protection architecture includes independent undervoltage lockout on VCC (4.3V falling), G1VCC–G1RTN (3.4V falling), and G2VCC–G2RTN (3.4V falling), plus overvoltage lockout on VCC (14.6V rising) and thermal shutdown (~180°C). Fault status is reported via open-drain FLT pin with 60Ω internal pull-down and 100µs delay on clear.

FAQ

What is the maximum allowable voltage difference between G1RTN and SGND for LTC7062EMSE#TRPBF?

The LTC7062EMSE#TRPBF supports a voltage difference of −10V to +100V between G1RTN and SGND. This specification enables operation in high-noise environments where ground bounce or switch-node transients cause significant offset - a key enabler for reliable high-side drive without isolation components. The same range applies to G2RTN vs SGND.

Does LTC7062EMSE#TRPBF provide shoot-through protection?

No, LTC7062EMSE#TRPBF does not include shoot-through protection. Unlike the LTC7060 and LTC7061 variants, the LTC7062EMSE#TRPBF has no internal logic to prevent simultaneous high-side and low-side conduction. System-level dead-time must be implemented externally in the controller or PWM generator driving G1IN and G2IN.

What is the purpose of the exposed pad (pin 13) on the LTC7062EMSE#TRPBF MSOP package?

The exposed pad (pin 13) on the LTC7062EMSE#TRPBF is SGND and must be soldered to the PCB ground plane. It serves dual functions: establishing low-impedance electrical reference for internal circuitry and dissipating heat - achieving the specified θ_JA = 40°C/W. Failure to solder this pad degrades thermal performance and risks junction overheating under load.

Can LTC7062EMSE#TRPBF drive logic-level MOSFETs?

Yes, LTC7062EMSE#TRPBF can drive logic-level MOSFETs. Its floating supply range of 4V to 14V per channel allows direct connection to logic-level gate thresholds (e.g., 4.5V or 5V), while the 1.5Ω pull-up and 0.8Ω pull-down ensure sufficient peak current (≥3A/6A at 10V) for fast turn-on/turn-off even with higher gate charge devices.

How does the FLT pin behave during fault conditions for LTC7062EMSE#TRPBF?

The FLT pin on LTC7062EMSE#TRPBF is an open-drain output pulled low to SGND immediately upon detection of VCC UVLO/OVLO, G1VCC–G1RTN UVLO, G2VCC–G2RTN UVLO, or thermal shutdown. After all faults clear, FLT returns high after a fixed 100µs internal delay - allowing clean system-level fault latching without external timers.
