Product details
Overview
LTC7062IMSE#WPBF 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 isolated half-bridge and synchronous boost applications.
For engineers reviewing the LTC7062IMSE#WPBF datasheet, LTC7062IMSE#WPBF pinout, LTC7062IMSE#WPBF application, or LTC7062IMSE#WPBF 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 MSOP-12 exposed-pad thermal performance.
Technical Context
The LTC7062IMSE#WPBF implements two fully symmetric, isolated high-side gate drivers with independent level-shifted logic control paths. Each channel features dedicated UVLO monitoring on its floating supply (G1VCC–G1RTN and G2VCC–G2RTN), with 3.4V threshold and 0.3V hysteresis, plus integrated 1000kΩ internal pull-downs on G1IN/G2IN to ensure default-low state when un-driven.
Its output stage uses P-channel (1.5Ω RDS(ON)) pull-up and N-channel (0.8Ω RDS(ON)) pull-down devices per channel, enabling 3A peak pull-up and 6A peak pull-down current at 10V supply - delivering 18ns rise time into 3.3nF load while maintaining <21ns propagation delay across –40°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Max | 100V input voltage rating - enables direct use in 48V–100V bus systems without external level-shifting. |
| VCC Range | 5V–14V - powers internal logic; generates 4.5V bias rail; independent of floating supplies. |
| G1/G2 Driver Supply | 4V–14V (G1VCC–G1RTN, G2VCC–G2RTN) - supports logic-level and high-threshold MOSFETs. |
| Pull-Up / Pull-Down R | 1.5Ω / 0.8Ω typical - delivers fast switching (14–18ns rise/fall) into 3nF loads. |
| UVLO Thresholds | VCC: 4.3V (falling); G1/G2 supplies: 3.4V - prevents erratic operation during brown-out. |
| Fault Indicator | Open-drain FLT pin with 60Ω internal pull-down - asserts low on VCC UVLO/OVLO, floating supply UVLO, or thermal shutdown. |
| Operating Temp | –40°C to +125°C junction - qualified for automotive-grade reliability (AEC-Q100 in progress). |
Pinout & Package
Package: 12-lead plastic MSOP with exposed thermal pad (pin 13 = SGND), θJA = 40°C/W. Exposed pad must be soldered to PCB ground for electrical integrity and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G1IN | Logic input for Channel 1 | TTL/CMOS-compatible; 1.75V turn-on / 0.5V turn-off threshold; 1000kΩ internal pull-down to SGND. |
| G2IN | Logic input for Channel 2 | Independent of G1IN; identical threshold and pull-down behavior. |
| FLT | Fault flag output | Open-drain to SGND; pulls low on VCC UVLO/OVLO, G1/G2 supply UVLO, or thermal shutdown. |
| NC | No connect | Pins 4 and 9 are unused; must remain unconnected. |
| VCC | IC bias supply | Powers internal circuitry; generates 4.5V bias rail; bypass with ≥0.1µF capacitor to SGND. |
| G2VCC | Channel 2 gate driver supply | Bias source for G2 output; referenced to G2RTN; requires local bypass capacitor. |
| G1VCC | Channel 1 gate driver supply | Bias source for G1 output; referenced to G1RTN; requires local bypass capacitor. |
| G1 | Channel 1 gate driver output | Swings between G1VCC and G1RTN; drives N-MOSFET gate; Kelvin-connected to MOSFET source via G1RTN. |
| G1RTN | Channel 1 return reference | Ground reference for G1 driver; tolerates –10V to +100V vs SGND; Kelvin connection critical for noise immunity. |
| G2 | Channel 2 gate driver output | Swings between G2VCC and G2RTN; drives second N-MOSFET gate. |
| G2RTN | Channel 2 return reference | Ground reference for G2 driver; same –10V to +100V tolerance as G1RTN. |
| SGND | Chip ground / thermal pad | Reference for VCC, FLT, and logic inputs; exposed pad (pin 13) must be soldered to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side drivers | Enables complementary or non-complementary switching in half-bridge, synchronous boost, and isolated DC/DC topologies. |
| ±10V ground difference tolerance | Supports robust operation in noisy environments where switch-node potentials differ significantly from system ground. |
| 100V absolute max input rating | Allows direct integration into 48V, 60V, and 100V industrial and automotive power systems without derating. |
| Thermal shutdown protection | Disables both outputs at ~180°C junction temperature; resumes operation below 165°C - prevents permanent damage. |
| Bootstrapped supply compatibility | G1VCC–G1RTN and G2VCC–G2RTN can be bootstrapped using external capacitors (e.g., 0.1µF) for high-side gate drive in buck-boost converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC7060EMSE#PBF | Includes programmable dead-time (31–76ns); shoot-through protection; same 100V rating and 1.5Ω/0.8Ω drive. | Required where precise timing control between high-side switches is mandatory (e.g., synchronous rectification). | Select LTC7060 when dead-time adjustment is needed; LTC7062IMSE#WPBF is preferred for simpler independent switching. |
| LTC7063HMSE#WPBF | 150V absolute max rating; otherwise identical architecture, pinout, and drive strength. | Suitable for >100V bus systems (e.g., 150V industrial DC links) where LTC7062IMSE#WPBF would exceed voltage limits. | Choose LTC7063HMSE#WPBF only if system VIN exceeds 100V; LTC7062IMSE#WPBF offers optimal cost/performance for ≤100V applications. |
Compared with LTC7060EMSE#PBF, LTC7062IMSE#WPBF omits dead-time programming but retains full floating-supply independence and noise immunity - simplifying layout and reducing BOM count. Versus LTC7063HMSE#WPBF, it trades 50V headroom for tighter thermal specs and lower cost in standard 48V–100V applications.

FAQ
What is the maximum allowable voltage difference between G1RTN/G2RTN and SGND for LTC7062IMSE#WPBF?
The LTC7062IMSE#WPBF supports a voltage difference of –10V to +100V between either G1RTN or G2RTN and SGND. This specification enables operation in high-noise environments with significant ground potential differences, such as automotive 48V systems with shared chassis ground and isolated power stages. The LTC7062IMSE#WPBF maintains functional integrity across this full range without latch-up or parametric degradation.
Does LTC7062IMSE#WPBF support bootstrapped gate drive configurations?
Yes, LTC7062IMSE#WPBF fully supports bootstrapped operation on both G1VCC–G1RTN and G2VCC–G2RTN supplies. An external capacitor (e.g., 0.1µF) is connected between each VCC and RTN pair, charged via an external Schottky diode from VCC. The LTC7062IMSE#WPBF does not charge the bootstrap capacitor itself but reliably drives the gate using the stored voltage - making it ideal for synchronous boost and high-side switch applications.
What fault conditions trigger the FLT pin on LTC7062IMSE#WPBF?
The FLT pin on LTC7062IMSE#WPBF is pulled low by an internal N-channel MOSFET under four confirmed fault conditions: (1) VCC falling below 4.3V or rising above 14.6V, (2) G1VCC–G1RTN dropping below 3.4V, (3) G2VCC–G2RTN dropping below 3.4V, or (4) junction temperature reaching ~180°C. After fault clearance, FLT returns high after a fixed 100µs delay - ensuring clean system-level fault signaling for LTC7062IMSE#WPBF-based designs.
Is LTC7062IMSE#WPBF pin-compatible with other members of the LTC706x family?
No, LTC7062IMSE#WPBF is not pin-compatible with LTC7060, LTC7061, or LTC7063. While all share the same 12-lead MSOP package and core pin functions (G1IN, G2IN, G1, G2, VCC, SGND, etc.), pin assignments differ - notably FLT, NC, and supply pins are repositioned across variants. Layout reuse is not possible; each part requires its own footprint. Always verify pin mapping using the official LTC7062IMSE#WPBF datasheet before PCB design.
What is the thermal resistance (θJA) of LTC7062IMSE#WPBF in its MSOP package?
The junction-to-ambient thermal resistance (θJA) of LTC7062IMSE#WPBF in the 12-lead plastic MSOP package with exposed pad is 40°C/W, measured under standard JEDEC 51-7 conditions with the exposed pad (pin 13 = SGND) fully soldered to a 1-inch² copper area on the PCB. Achieving this value requires strict adherence to recommended layout practices - including short, wide traces to SGND, proper bypassing, and full thermal pad soldering. Failure to implement these reduces effective heat dissipation.
