Product details
Overview
LTC7063RMSE#WPBF from Analog Devices is a 150V 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 48V–75V telecom and industrial DC/DC converters.
For engineers reviewing the LTC7063RMSE#WPBF datasheet, LTC7063RMSE#WPBF pinout, LTC7063RMSE#WPBF application, or LTC7063RMSE#WPBF equivalent, key selection criteria include its ±10V ground differential tolerance, AEC-Q100 qualification, 12-lead thermally enhanced MSOP package with exposed SGND pad, and support for 4V–14V gate drive supplies independent of VCC.
Technical Context
The LTC7063RMSE#WPBF implements a symmetric double-floating architecture: both high-side (TG/SW/BST) and low-side (BG/BGRTN/BGVCC) driver sections operate with independent ground references, enabling robust operation under large ground potential differences. Its three-state PWM input (with internal 48kΩ pull-up and 42kΩ pull-down) supports high-Z disable mode, while EN pin provides synchronous enable/disable control.
Adaptive shoot-through protection monitors gate-source voltage transitions to prevent simultaneous conduction; dead-time is precisely set via DT pin resistor (32ns to 250ns range). UVLO/OVLO protection applies separately to VCC (5.3V/14.6V thresholds), BST–SW, and BGVCC–BGRTN (3.4V UVLO each), with open-drain FLT output signaling faults.
Key Specifications

FAQ
What is the maximum allowable voltage difference between SGND and SW or BGRTN for the LTC7063RMSE#WPBF?
The LTC7063RMSE#WPBF supports a voltage difference of –10V to +150V between SGND and SW, and –10V to +150V between SGND and BGRTN. This ±10V ground differential tolerance enables robust operation in high-noise environments such as motor drives and isolated DC/DC converters where ground loops induce significant offsets. The specification is validated across the full –40°C to +150°C operating junction temperature range.
How does the DT pin on the LTC7063RMSE#WPBF configure dead-time, and what resistor values correspond to common settings?
The DT pin on the LTC7063RMSE#WPBF sets dead-time by connecting an external resistor to SGND. Dead-time follows DT = RDT × 0.44 ns/kΩ + 32 ns for RDT < 100 kΩ. For example, 24.9 kΩ yields ~43 ns, 64.9 kΩ yields ~62 ns, and 100 kΩ yields ~76 ns. An open DT pin gives ~250 ns; shorting to SGND gives the minimum 32 ns. This resistor-programmed flexibility allows optimization for specific MOSFET Qg and switching frequency.
Does the LTC7063RMSE#WPBF require external bootstrap diodes or charge pumps for high-side drive?
No, the LTC7063RMSE#WPBF does not integrate or require external bootstrap diodes or charge pumps. It relies on externally supplied floating gate drive voltages: BST–SW (4–14V) for the high-side driver and BGVCC–BGRTN (4–14V) for the low-side driver. These supplies must be generated externally - typically via bootstrap capacitors charged through Schottky diodes from VCC or other bias rails - and monitored independently by the IC's UVLO circuitry.
What fault conditions trigger the FLT pin on the LTC7063RMSE#WPBF, and how is recovery handled?
The FLT pin on the LTC7063RMSE#WPBF pulls low during VCC UVLO (<5.3V) or OVLO (>14.6V), BST–SW UVLO (<3.4V), BGVCC–BGRTN UVLO (<3.4V), or junction temperature ≥180°C. After all fault conditions clear, FLT releases after a fixed 100 µs internal delay and is pulled high by the external pull-up resistor. The 60Ω typical pull-down resistance ensures fast, low-impedance fault signaling to system controllers.
Is the LTC7063RMSE#WPBF pin-compatible with other members of the LTC706x family, such as the LTC7060 or LTC7062?
No, the LTC7063RMSE#WPBF is not pin-compatible with LTC7060 or LTC7062. While all share the 12-lead MSOP package, pin functions differ significantly: LTC7060/LTC7062 lack the DT pin and three-state PWM architecture, and assign different roles to Pins 4 (DT vs. NC) and 5 (VCC vs. EN). Substituting requires PCB layout changes and firmware adaptation to match the distinct control interface and protection behavior of each variant.
