Product details
Overview
DGD2190MS8-13 from Diodes Incorporated is a high-voltage, high-speed dual-channel gate driver IC for half-bridge N-channel MOSFET/IGBT configurations, featuring 600V high-side floating capability, 4.5A typical sink/source output current, and TTL/CMOS-compatible 3.3V logic inputs. It operates across –40°C to +125°C and is used in DC-DC converters, motor controls, and Class D amplifiers where robust bootstrap-based high-side switching is required.
For engineers reviewing the DGD2190MS8-13 datasheet, DGD2190MS8-13 pinout, DGD2190MS8-13 application, or DGD2190MS8-13 equivalent, key selection criteria include high dV/dt immunity (50 V/ns), matched propagation delays (≤50 ns), undervoltage lockout thresholds (7.6–9.8 V), and SO-8 thermal performance (RθJA = 200 °C/W).
Technical Context
The DGD2190MS8-13 integrates independent high-side and low-side drivers with isolated floating supply (VB/VS) architecture enabling 600V bootstrap operation. Its Schmitt-triggered HIN/LIN inputs provide noise immunity, while internal UVLO circuits protect both channels at separate 7.6–9.8 V thresholds with 0.6 V hysteresis.
AC timing is tightly controlled: tON/tOFF typ. 140 ns (VS = 0 V), rise/fall times of 25–50 ns and 20–45 ns respectively, and delay matching ≤50 ns between HO and LO outputs - critical for minimizing shoot-through in high-frequency half-bridge switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-Side Voltage Rating | 600 V max VS offset - enables use in 400 V DC bus systems with margin |
| Output Drive Current | 4.5 A typ. sink/source - supports fast turn-on/off of high-Qg MOSFETs |
| Logic Input Compatibility | 3.3 V–5 V TTL/CMOS - interfaces directly with microcontrollers and PWM controllers |
| Propagation Delay Match | ≤50 ns difference between HO/LO - reduces dead-time uncertainty in gate timing |
| UVLO Thresholds | VCC/VBS UV+ = 7.6–9.8 V, hysteresis = 0.6 V - prevents erratic switching during brown-out |
| Operating Temperature | –40°C to +125°C ambient - qualified for industrial and automotive under-hood environments |
| dV/dt Immunity | 50 V/ns on VS node - maintains high-side functionality under fast transient conditions |
Pinout & Package
Supplied in an SO-8 (Type TH) surface-mount package with matte tin-plated leads, moisture sensitivity level 3, and UL 94V-0 rated molding compound. Weight: 0.075 g.

| 2 LIN | Low-side logic input | In-phase control signal for LO; Schmitt-triggered, internal pull-down |
| 3 COM | Low-side return reference | Common ground for VCC, LO, and logic circuitry |
| 4 LO | Low-side gate drive output | Drives N-MOSFET source-connected to COM; 4.5 A sink capability |
| 5 VCC | Fixed low-side supply | 10–20 V bias for low-side driver and logic; includes UVLO |
| 6 VS | High-side floating return | Reference for high-side driver; tracks source of high-side MOSFET |
| 7 HO | High-side gate drive output | Drives N-MOSFET gate referenced to VS; 4.5 A source capability |
| 8 VB | High-side floating supply | Bootstrap-supplied voltage up to 600 V above VS; powers high-side driver |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side/low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS21844STRPBF | Higher VBS UVLO threshold (10.1 V), slower tON/tOFF (210 ns typ.), SO-8 package | Limited to lower dV/dt environments (<25 V/ns); less suitable for 600 V fast-switching topologies | Prefer when system-level UVLO margin must exceed 10 V and timing precision is secondary |
| LM5109BMAX/NOPB | Lower peak output current (1.5 A), no integrated Schmitt trigger, MSOP-8 package | Requires external input conditioning; unsuitable for noisy motor drive environments without added filtering | Choose only for cost-sensitive, low-power half-bridge designs with clean control signals |
Compared with IRS21844STRPBF and LM5109BMAX/NOPB, the DGD2190MS8-13 delivers superior dV/dt immunity, tighter timing matching, and higher drive strength - making it optimal for high-reliability, high-frequency half-bridge systems requiring minimal external components.

FAQ
What is the maximum allowable dV/dt on the VS pin?
The DGD2190MS8-13 is rated for 50 V/ns on the VS pin under transient conditions, verified per Absolute Maximum Ratings. This specification ensures reliable high-side operation during fast switching transitions in 400–600 V bus applications without false triggering or latch-up.
Does the device require external bootstrap diode and capacitor?
Yes - the DGD2190MS8-13 requires an external bootstrap diode and capacitor between VB and VS to generate the floating high-side supply. The datasheet specifies minimum capacitance (typically ≥0.1 µF ceramic) and recommends fast-recovery diodes with low reverse recovery charge.
Can HIN and LIN be driven independently for non-complementary operation?
Yes - HIN and LIN are fully independent logic inputs with internal pull-down resistors. They can be driven separately to implement three-state control, shoot-through prevention logic, or asymmetric PWM schemes without cross-talk or unintended conduction.
Is the SO-8 package thermally adequate for continuous 4.5 A output operation?
At 4.5 A peak, junction temperature rise depends on PCB layout: on a standard 2-layer JEDEC board, RθJA = 200 °C/W limits continuous dissipation to ~0.625 W. For sustained high-current operation, thermal vias under the exposed pad (if present) and copper pour are strongly recommended to reduce θJA below 100 °C/W.
