UCC23513BQDWYRQ1 Descripción general
An isolated gate driver is a critical component in power electronics, providing galvanic isolation between low-voltage control logic and high-voltage power switching devices. Gate drivers fall within the broader category of power management and driver ICs, serving as the interface between microcontrollers, DSPs, or gate-driver controllers and the high-current gates of IGBTs, MOSFETs, and SiC FETs. The UCC23513BQDWYRQ1 uses TI's proprietary capacitive isolation technology to achieve 5.7 kV RMS reinforced isolation with low propagation delay and high common-mode transient immunity, making it functionally pin-compatible with traditional opto-isolated gate drivers while delivering superior reliability and temperature performance.
Key features include 4.5 A source / 5.3 A sink peak output current, 105 ns typical propagation delay, 35 ns part-to-part delay matching, 100 kV/us minimum common-mode transient immunity (CMTI), and 8 mm creepage/clearance package design. The device supports bipolar supply operation for driving IGBTs and SiC FETs requiring negative gate drive voltage. Its UVLO threshold of 8 V (typical) protects power switches against insufficient drive voltage. The wide operating temperature range of -40°C to +125°C suits automotive under-hood and industrial environments.
Typical applications include automotive traction inverters, on-board chargers (OBC), DC fast charging stations, industrial motor drives, solar inverters, and server/telecom power supplies. Its opto-compatible input stage allows direct replacement of HCPL-3120-style optocouplers in existing designs without PCB changes, simplifying upgrades from older discrete isolator solutions to modern integrated gate drivers.
When designing with this part, ensure that the local VCC bypass capacitance (typically 1 uF to 10 uF ceramic) is placed within 2 mm of the VCC pin. Account for the bootstrap supply current in high-side configurations, and never exceed the 33 V absolute maximum VCC rating. The driver's input is current-driven like an optocoupler, requiring the designer's choice of input LED current-limiting resistor.

Notas de diseño
Estimate (input voltage 18 V, output 0 V, no load): the UCC23513BQDWYRQ1 quiescent supply current is approximately 1.5 mA per datasheet. Place a 1 uF to 10 uF low-ESR ceramic bypass capacitor (X7R or X7S dielectric) directly across VDD to GND within 2 mm of the pins to suppress high-frequency switching transients. The bootstrap supply current in high-side applications is significant and must be accounted for in the bootstrap capacitor selection, typically 10 uF minimum with a 5 mW to 10 mW constant current draw. Use a unidirectional TVS diode to clamp inductive transients below the 33 V absolute maximum VCC rating.
At switching frequencies above 50 kHz in a 6-SOIC (DWY) package, estimate: power dissipation reaches 50 mW per gate driver switching 1 nC total gate charge at 100 kHz. The thermal resistance of the 6-SOIC with the exposed paddle is approximately 70 C/W, yielding a modest 3.5 C junction-temperature rise per gate. When multiple drivers are placed in close proximity, ensure at least 5 mm clearance between packages to allow copper-pour thermal spreading. AEC-Q100 applications require derating to maintain junction below 150 C over the full automotive temperature range.
Maintain 8 mm creepage and clearance distance between the high-voltage side (output) and low-voltage side (input) of the UCC23513BQDWYRQ1 package per IEC 60664-1. Avoid placing any copper traces or vias underneath the package body between the input and output sides, since the silicon dioxide isolation barrier is the primary insulator. Place the VDD bypass capacitor and gate-drive resistor network within 5 mm of the OUT pin to minimize parasitic loop inductance. For multilayer PCB stack-ups, dedicate an internal layer to a continuous ground plane beneath the device to reduce common-mode noise coupling across the isolation barrier.
Estimate (gate resistance 10 ohm, 6.5 nC gate charge): expected gate rise time is roughly 6 ns for SiC FETs. Use a series gate resistor of 2.2 ohm to 10 ohm to dampen parasitic ringing between the gate-source capacitance and the circuit-board inductance. Add a Kelvin source connection from the gate-driver ground to the power-switch source to avoid ground bounce from high di/dt return currents. The opto-compatible input is current-driven; use a current-limiting resistor sized for 7 mA to 15 mA of input drive current matched to the logic-level PWM signal amplitude.
Never operate the UCC23513BQDWYRQ1 input below the minimum input diode forward current (about 5 mA); below this threshold, propagation delay increases and input jitter becomes unpredictable. Do not connect VDD below the 8 V UVLO threshold or above 33 V absolute-max. Do not assume 5 V operation is possible — the part requires a minimum 9.5 V supply. Avoid placing ferrite beads in the gate-drive loop, since their parasitic inductance can produce voltage overshoot exceeding the gate-driver output rating during high di/dt switching events.
