Analog Devices Inc. LTC7062IMSE#WTRPBF

Overview

LTC7062IMSE#WTRPBF 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 automotive and industrial high-noise DC/DC converters operating up to 100V input.

For engineers reviewing the LTC7062IMSE#WTRPBF datasheet, LTC7062IMSE#WTRPBF pinout, LTC7062IMSE#WTRPBF application, or LTC7062IMSE#WTRPBF equivalent, key selection considerations include floating supply voltage range (4V–14V per channel), ±10V ground difference tolerance, thermal shutdown at ~180°C, UVLO thresholds (4.3V VCC, 3.4V per gate supply), and MSOP-12 exposed-pad thermal performance.

Technical Context

The LTC7062IMSE#WTRPBF implements two fully symmetric, isolated high-side gate drivers-each with independent level-shifted logic control, dedicated UVLO monitoring on G1VCC–G1RTN and G2VCC–G2RTN, and rail-to-rail output swing referenced to its own return pin. Its architecture eliminates shoot-through risk by design (no integrated dead-time control) and supports complementary or non-complementary switching.

Each channel features a 1.5Ω P-channel pull-up and 0.8Ω N-channel pull-down stage capable of delivering ~3A peak pull-up and ~6A peak pull-down current at 10V supply, enabling fast turn-on/off of high-threshold MOSFETs with ≤3nF gate load (18ns rise, 14ns fall). Fault detection covers VCC UVLO/OVLO (4.3V/14.6V), floating supply UVLO (3.4V), and thermal shutdown (~180°C).

Key Specifications

Pinout & Package

Package: 12-lead plastic MSOP with exposed thermal pad (pin 13 = SGND), θ_JA = 40°C/W. Exposed pad must be soldered to PCB ground for thermal and electrical integrity.

FAQ

What is the maximum input voltage the LTC7062IMSE#WTRPBF can handle?

The LTC7062IMSE#WTRPBF supports up to 100V on its high-side gate driver inputs (G1VCC–G1RTN and G2VCC–G2RTN), with absolute maximum ratings of 115V. Its VCC supply operates from 5V to 14V independently. This allows direct integration into 48V, 60V, and 100V DC/DC systems without external level-shifting circuitry. The LTC7062IMSE#WTRPBF maintains full functionality across this range while tolerating ±10V ground differences between its floating returns and system ground.

Does the LTC7062IMSE#WTRPBF provide shoot-through protection?

No, the LTC7062IMSE#WTRPBF does not include integrated shoot-through protection or programmable dead-time. It is designed for independent, symmetric high-side control - enabling complementary or non-complementary switching based on external controller logic. For shoot-through-critical applications like half-bridge inverters, Analog Devices recommends the LTC7060IMSE#WTRPBF or LTC7061IMSE#WTRPBF, which feature adjustable dead-time (31–76ns) and explicit shoot-through prevention. The LTC7062IMSE#WTRPBF relies on external timing control for safe operation.

How does the FLT pin on the LTC7062IMSE#WTRPBF behave during faults?

The FLT pin on the LTC7062IMSE#WTRPBF is an open-drain output pulled low (to SGND) when any of these conditions occur: VCC UVLO (<4.3V) or OVLO (>14.6V), G1VCC–G1RTN UVLO (<3.4V), G2VCC–G2RTN UVLO (<3.4V), or thermal shutdown (~180°C). After fault clearance, FLT releases after a fixed 100µs delay and is pulled high by an external resistor (e.g., 51kΩ to VCC). This behavior is documented in the LTC7062IMSE#WTRPBF datasheet Table 1 and timing diagram Figure 7062 TD.

Can the LTC7062IMSE#WTRPBF drive logic-level MOSFETs?

Yes, the LTC7062IMSE#WTRPBF can drive logic-level MOSFETs, as its gate driver supply range is 4V to 14V per channel (G1VCC–G1RTN and G2VCC–G2RTN). At 4.5V minimum, it meets the V_GS(th) requirements of most logic-level N-channel devices. However, drive strength scales with supply voltage: pull-up/pull-down resistance increases below 6V, reducing peak current. For optimal performance with logic-level FETs, operate G1VCC–G1RTN and G2VCC–G2RTN at ≥5V. The LTC7062IMSE#WTRPBF is characterized and optimized for 10V operation.

What is the thermal performance of the LTC7062IMSE#WTRPBF in MSOP-12 package?

The LTC7062IMSE#WTRPBF in the 12-lead MSOP package has a specified junction-to-ambient thermal resistance (θ_JA) of 40°C/W when the exposed pad (pin 13 = SGND) is properly soldered to a minimum 1-inch² copper area on the PCB. Junction temperature is calculated as T_J = T_A + (P_D × 40°C/W). The device is rated for −40°C to +125°C operating junction temperature and includes thermal shutdown at ~180°C. Failure to solder the exposed pad degrades thermal performance significantly - the LTC7062IMSE#WTRPBF requires this connection for rated reliability.
