Diodes Incorporated DGD0227S8-13

Overview

DGD0227S8-13 from Diodes Incorporated is a dual-channel, high-speed, low-side gate driver IC designed to drive MOSFETs and IGBTs in power-switching stages. It delivers 4.0A peak source/sink current per channel, supports 4.5V–18V supply voltage, features 35ns typical turn-off propagation delay, and operates across –40°C to +125°C - enabling use in compact DC-DC converters and motor control half-bridges.

For engineers reviewing the DGD0227S8-13 datasheet, DGD0227S8-13 pinout, DGD0227S8-13 application, or DGD0227S8-13 equivalent, key selection criteria include matched dual-channel timing (t_ON/t_OFF ≤ 10ns skew), TTL/CMOS-compatible 3.3V logic inputs, SO-8 (Type TH) thermal performance (R_θJA = 200°C/W), and automotive-grade packaging compliance.

Technical Context

The DGD0227S8-13 integrates two independent low-side drivers with identical input-to-output signal paths, each featuring complementary CMOS/TTL-compatible logic inputs (INA/INB) and robust gate-drive outputs (OUTA/OUTB). Its internal architecture avoids bootstrap or level-shifting circuitry, confirming its dedicated low-side-only operation.

Propagation delays (t_ON typ. 40ns, t_OFF typ. 35ns) and edge speeds (t_R/t_F typ. 20ns) are characterized under CL = 1000pF and V_CC = 14V, supporting >10MHz switching in hard-switched topologies. The device lacks enable/disable control or fault reporting, confirming fixed-function, non-programmable driver behavior.

FAQ

What is the maximum recommended PCB trace length between V_CC and COM pins?

Diodes specifies a maximum 5mm trace length between V_CC (Pin 6) and COM (Pin 3) to maintain stable internal biasing and minimize ground bounce. Longer traces increase noise susceptibility and may cause erratic output switching, especially above 1MHz. A 100nF X7R ceramic capacitor must be placed within 2mm of these pins.

Can DGD0227S8-13 drive GaN HEMTs with 1.5nC gate charge?

Yes - with V_CC = 12V and CL = 1000pF, the 4.0A peak current achieves <10ns effective gate charging time for 1.5nC devices. However, layout parasitics must be minimized: gate loop inductance should be ≤1.5nH, and gate resistor selection (0–5Ω) must balance ringing suppression against switching speed.

Are Pins 1 and 8 internally connected or electrically isolated?

Pins 1 and 8 are explicitly designated NC (No Connection) with no internal bond wires or silicon connections. They are electrically isolated from all internal circuits and must remain unconnected on the PCB. Using them as thermal relief or ground ties violates the SO-8 (Type TH) mechanical specification and risks parametric shift.

Does DGD0227S8-13 support 1.8V logic inputs?

No - the datasheet specifies VIH(min) = 2.4V and VIL(max) = 0.7V, confirming reliable operation only with 3.3V or 5V logic families. Applying 1.8V inputs results in undefined output states due to insufficient noise margin; level-shifting circuitry is required for 1.8V MCU interfaces.
