Product details
Overview
DGD1503S8-13 from Diodes Incorporated is a half-bridge gate driver IC designed to control two N-channel MOSFETs or IGBTs in high-voltage switching topologies. It features a floating high-side driver capable of bootstrap operation up to 250V, 290mA source / 600mA sink output current, fixed 430ns internal deadtime, and TTL/CMOS-compatible logic inputs down to 3.3V. It supports DC-DC converters and motor control systems operating from –40°C to +125°C in SO-8 package.
For engineers reviewing the DGD1503S8-13 datasheet, DGD1503S8-13 pinout, DGD1503S8-13 application, or DGD1503S8-13 equivalent, key selection criteria include high-side voltage capability (250V), output drive strength (290mA/600mA), internal deadtime (430ns), logic-level compatibility (3.3V), and thermal robustness (–40°C to +125°C).
Technical Context
The DGD1503S8-13 implements independent high-side and low-side drivers with separate supply domains: VB/VS for high-side floating bias and VCC for logic/low-side. Its Schmitt-triggered HIN/LIN* inputs reject noise and support fast edge transitions, while undervoltage lockout (UVLO) protects both VCC (7.4–9.6V threshold) and VB/VS (5.5–7.5V) rails.
Propagation delays are asymmetrically optimized: tON = 680–820ns (VS = 0V), tOFF = 150–220ns (VS = 250V), enabling precise timing control in hard-switching applications. The 300–550ns deadtime window prevents shoot-through during bridge commutation, and outputs tolerate negative transients on LO/COM and HO/VS paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | 250V max bootstrap operation - enables use in 200V-class DC bus systems with margin |
| Output Drive Strength | 290mA source / 600mA sink - sufficient to rapidly charge/discharge 1nF gate capacitance in <100ns |
| Internal Deadtime | 430ns typical - prevents simultaneous conduction in half-bridge without external timing circuitry |
| Logic Input Compatibility | 3.3V–5V TTL/CMOS - interfaces directly with microcontrollers, FPGAs, and PWM controllers |
| Operating Temperature | –40°C to +125°C - supports under-hood automotive and industrial power conversion environments |
| Supply Voltage Range | VCC: 10V–20V; VB–VS: 10V–20V - accommodates wide input rail variations in SMPS designs |
| UVLO Thresholds | VCCUV+: 7.4–9.6V; VBSUV+: 5.5–7.5V - ensures reliable startup and fault shutdown across temperature |
Pinout & Package
Package: SO-8 (Type TH), surface-mount, lead-free, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Logic and low-side supply input | Provides power for internal logic and low-side driver stage; requires local 10–20V decoupling |
| 2 HIN | High-side logic input | In-phase control signal for HO output; Schmitt-triggered for noise immunity |
| 3 LIN* | Low-side logic input (active-low) | Out-of-phase control for LO output; * denotes active-low polarity |
| 4 COM | Low-side and logic ground return | Common reference for VCC, LIN*, and LO; must be low-inductance connection to PCB ground plane |
| 5 LO | Low-side gate drive output | Drives N-MOSFET/IGBT gate referenced to COM; rated for 600mA sink |
| 6 VS | High-side floating supply return | Reference node for high-side driver; connects to source of high-side switch in bootstrap configuration |
| 7 HO | High-side gate drive output | Drives gate of high-side N-MOSFET/IGBT referenced to VS; rated for 290mA source |
| 8 VB | High-side floating supply input | Bias supply for high-side driver; connected to bootstrap capacitor top node |
Key Features
| Feature | Design Value |
|---|---|
| Floating high-side driver | Supports bootstrap operation up to 250V VS offset - eliminates need for isolated bias supplies in half-bridge inverters |
| Integrated deadtime | 430ns fixed internal delay - prevents cross-conduction without external timing components or controller firmware overhead |
| Negative transient tolerance | Outputs withstand –5V undershoot on LO/COM and HO/VS - improves reliability in noisy motor-drive and inverter environments |
| Wide VCC range | 10V–20V operation - allows direct use with 12V or 15V system rails without LDO regulation |
| Schmitt-trigger inputs | HIN/LIN* thresholds: VIH ≥2.5V, VIL ≤0.8V - rejects >1V of common-mode noise on control lines |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DGD2003S8-13 | Successor part with enhanced 300V high-side rating, lower 350ns deadtime, and improved UVLO hysteresis | Same SO-8 footprint; supports higher DC bus voltages and faster switching in new designs | Select for new designs requiring extended voltage margin and tighter timing control |
| IRS2004STRPBF | Infineon part with 600V high-side rating, but requires external deadtime circuitry and has higher quiescent current (1.2mA) | Used in industrial inverters where >250V headroom is mandatory; lacks integrated deadtime | Choose only when 600V capability is required and external timing control is acceptable |
Compared with DGD1503S8-13, DGD2003S8-13 offers higher voltage headroom and tighter deadtime for next-gen designs, while IRS2004STRPBF provides greater voltage scalability at the cost of added external components and higher static power.

FAQ
Is DGD1503S8-13 still in production?
No - Diodes Incorporated has officially discontinued the DGD1503S8-13 and designated it as obsolete. It is superseded by the DGD2003S8-13. However, Aetrix Electronics maintains limited legacy stock for ongoing maintenance, repair, and obsolescence mitigation programs with full traceability and documentation.
Can DGD1503S8-13 drive IGBTs reliably?
Yes - the DGD1503S8-13 is explicitly qualified to drive N-channel IGBTs in half-bridge configurations. Its 600mA sink and 290mA source output currents meet typical IGBT gate charge requirements for devices up to 50A/600V, and its negative transient tolerance on LO/COM enhances ruggedness in inductive switching environments.
What is the minimum recommended pulse width for HIN/LIN* inputs?
The datasheet specifies a minimum input pulse width of 860ns for reliable logic recognition. This ensures proper latching and propagation through internal Schmitt triggers and timing circuits, especially under worst-case voltage and temperature conditions (-40°C to +125°C, VCC = 10V).
Does DGD1503S8-13 require external bootstrap diode and capacitor?
Yes - the DGD1503S8-13 relies on an external bootstrap network: a fast-recovery diode (e.g., 1N4148WS) and a minimum 0.1µF ceramic capacitor between VB and VS. This network replenishes the high-side floating supply during each switching cycle and must be placed close to pins 6 (VS) and 8 (VB) to minimize loop inductance.
