Product details
Overview
DPS1133FIA-13 from Diodes Incorporated is a 1-channel 24V/3A hot-swap power switch with integrated MOSFET (RDS(ON) = 30 mΩ), fast role swap compliance per USB PD 3.0 v1.0a, and programmable current limit (up to 3.24 A), overvoltage protection (up to 24.5 V), and output voltage ramp control. It enables robust port power management in USB-C docking stations and industrial hot-plug interfaces.
For engineers reviewing the DPS1133FIA-13 datasheet, DPS1133FIA-13 pinout, DPS1133FIA-13 application, or DPS1133FIA-13 equivalent, key selection criteria include its 2 µs short-circuit response time, dual-port discharge control (DISC1/DISC2), fault blanking (7 ms), and adjustable DV/DT slew rate for in-rush current limiting in high-capacitance systems.
Technical Context
The DPS1133 implements a single N-channel MOSFET power switch with analog-programmable protection thresholds: ILIM set via resistor on ILIM pin (27–200 kΩ), VLIM via resistor on VLIM pin (51–270 kΩ), and DV/DT slew rate via capacitor on DV/DT pin (typ. 1 µA bias, 12 V/V gain). It integrates reverse-voltage protection triggered at –30 mV (VIN – VOUT) with 2 µs response.
Its fault architecture combines fast-trip OCP (IFASTRIP = 1.125 × ILIM + 1.8 A), thermal shutdown at +165 °C with +20 °C hysteresis, and active-low FAULTB with internal 25 Ω pull-down and 7 ms deglitch. The device supports simultaneous or independent IN/OUT port discharge via dedicated DISC1/DISC2 pins and complies with USB PD 3.0 Fast Role Swap timing (tDON_FRS ≤ 60 µs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5 V to 24 V input range - supports universal USB-C PD source/sink operation and industrial 12/24 V rail compatibility. |
| Continuous Current | 3.5 A max - sustains full-load operation under worst-case thermal conditions (TJ ≤ 125 °C). |
| RDS(ON) | 30 mΩ typ. at VIN = 24 V - minimizes conduction loss (≤ 315 mW at 3 A) and self-heating during sustained load. |
| Short-Circuit Response | 2 µs - ensures immediate MOSFET turn-off before energy dissipation damages downstream components or PCB traces. |
| Fault Blanking | 7 ms - prevents false FAULTB assertion during transient in-rush or capacitive charging events. |
| Thermal Shutdown | +165 °C with +20 °C hysteresis - guarantees automatic recovery after ambient cooling without manual reset. |
| Fast Role Swap Delay | ≤ 60 µs - meets USB PD 3.0 v1.0a tDON_FRS requirement for seamless DFP/UFP role transition. |
Pinout & Package
Housed in a 4.0 mm × 4.0 mm, 17-pin V-QFN4040-17 package with exposed thermal pad (SRC), the DPS1133FIA-13 provides low-profile mounting and enhanced thermal performance (RθJA = 58.5 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 IN | Power Input | High-current input port; accepts 4.5–24 V supply; paralleled pins reduce trace resistance and improve current sharing. |
| 4 EN | Enable Control | Active-high logic input; must be driven - floating state disables device; threshold: 1.4 V (high), 0.4 V (low). |
| 5 FRS | Fast Role Swap Trigger | Initiates USB PD-compliant role swap sequence; rising edge starts <60 µs turn-on delay to OUT. |
| 6 GND | Signal & Power Ground | Reference for all analog controls and fault reporting; connects to PCB ground plane under exposed pad. |
| 7 VREG | Internal Regulator Output | 5.1 V regulated supply (±0.2 V); requires 0.1 µF decoupling to GND for stable bias of external circuits. |
| 8 DISC1 | IN Port Discharge Enable | Active-high control for discharging IN port to GND via internal 105 Ω switch; used for USB PD port reset. |
| 9 DISC2 | OUT Port Discharge Enable | Active-high control for discharging OUT port to GND via internal 115 Ω switch; ensures safe disconnect per spec. |
| 10 FAULTB | Open-Drain Fault Flag | Active-low status output; sinks 10 mA; internal 25 Ω pull-down ensures defined state when unused. |
| 11 IMON | Current Monitor Output | Analog voltage proportional to IOUT (10 µA/A gain); requires RIMON//CIMON filter for stable DC reading. |
| 12 DV/DT | Ramp Rate Control | Sets output slew rate via external capacitor; 1 µA bias current × 12 V/V gain defines dV/dt slope. |
| 13 ILIM | Current Limit Set | Resistor-to-GND sets overcurrent threshold (ILIM = 100 / RILIM A); 27–200 kΩ range yields 0.5–3.24 A. |
| 14 VLIM | Voltage Limit Set | Resistor-to-GND sets input overvoltage threshold (VOVPRTH = 0.1 × RVLIM + 0.5 V); 51–270 kΩ → 5.6–24.5 V. |
| 15, 16, 17 OUT | Power Output | High-current output port; paralleled pins minimize voltage drop and thermal stress under 3.5 A load. |
| 18 (EP) SRC | Common Source Node | Exposed thermal pad; must be soldered to PCB ground plane for thermal conduction and EMI reduction - no signal connection. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Current Limit | Adjustable 0.5–3.24 A via single resistor on ILIM pin - eliminates need for external current-sense amplifier or shunt calibration. |
| Dual Independent Port Discharge | Dedicated DISC1/DISC2 pins enable selective or simultaneous IN/OUT discharge - satisfies USB PD specification port reset requirements. |
| USB PD 3.0 Fast Role Swap | Hardware-accelerated role swap with ≤60 µs output turn-on delay - enables compliant DFP↔UFP transitions without firmware intervention. |
| Reverse-Voltage Protection | Automatic MOSFET turn-off at –30 mV (VIN – VOUT) with 2 µs response - prevents backfeed damage in multi-source systems. |
| Adjustable Output Slew Rate | DV/DT pin controls dV/dt via external capacitor (e.g., 6.8 nF → ~1.7 V/ms at 20 V) - limits in-rush current into large COUT banks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1-channel hot-swap power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS25750RWER | Integrated USB PD controller + power switch; supports full PD policy engine and CC communication; higher BOM cost and complexity. | Required for full USB PD sink/source negotiation; not suitable for simple fixed-role power switching. | Select only if USB PD contract negotiation (e.g., voltage/current request/response) is needed - DPS1133FIA-13 is optimal for fixed-policy or legacy PD 2.0 systems. |
| RTQ2133GSP | 36 V max input, 4.5 A continuous, but lacks Fast Role Swap hardware support and dual-port discharge control. | Used in industrial 24 V systems where USB PD compliance is unnecessary and higher current is prioritized. | Choose when >3.5 A load capability is critical and USB PD 3.0 FRS is not required - DPS1133FIA-13 offers tighter integration for USB-C ecosystems. |
Compared with TPS25750RWER and RTQ2133GSP, the DPS1133FIA-13 delivers USB PD 3.0 Fast Role Swap in a cost-optimized, single-function package - ideal for fixed-role docking stations and industrial hot-swap where policy engine overhead is unnecessary and dual-port discharge is mandatory.

FAQ
What is the maximum continuous output current supported by DPS1133FIA-13?
The DPS1133FIA-13 supports 3.5 A continuous output current under recommended operating conditions (TA = +25°C, 2 oz copper PCB, 1" × 1" thermal pad). At elevated ambient temperatures or reduced copper area, derating applies - e.g., 3 A max at TA = +85°C per thermal characterization data in DS39393 Rev.11.
How is the overvoltage protection threshold set on DPS1133FIA-13?
The input overvoltage threshold (VOVPRTH) is set by an external resistor (RVLIM) between VLIM pin and GND: VOVPRTH = 0.1 × RVLIM + 0.5 V. With RVLIM = 240 kΩ, VOVPRTH = 24.5 V (rising) and 24.0 V (falling), enabling precise alignment with 24 V system rails and USB PD 3.0 specifications.
Does DPS1133FIA-13 require external components for basic operation?
Yes - minimum external components include: 0.1 µF capacitor on VREG–GND, pull-up resistor on FAULTB, and optional RILIM/RVLIM/CDV/DT for current/voltage/ramp control. The device operates without them (defaults to ~1 A ILIM, ~6 V OVP, and fast ramp), but full feature utilization requires these passive elements per DS39393 Section 8.
Can DPS1133FIA-13 be used in automotive applications?
The DPS1133FIA-13 is qualified to J-STD-020 moisture sensitivity Level 1 and meets IEC60950-1 CB Scheme requirements, but it is not AEC-Q100 qualified. For automotive use, Diodes recommends contacting their sales team for PPAP-capable variants manufactured in IATF 16949 facilities - this specific part is intended for industrial and computing applications.
