Product details
Overview
PI3PD22919GBEX from Diodes Incorporated (acquired Pericom in 2017) is an ultra-low RON N-channel load switch optimized for low-input-voltage power rail control in portable electronics. It operates from 0.75 V to 3.6 V, delivers up to 4 A continuous current, achieves 7.1 mΩ typical RON at 3.6 V, and integrates quick output discharge with a 1250 Ω pulldown resistor - used in smartphone PMIC output staging and USB-powered peripheral enable paths.
For engineers reviewing the PI3PD22919GBEX datasheet, PI3PD22919GBEX pinout, PI3PD22919GBEX application, or PI3PD22919GBEX equivalent, key selection criteria include sub-1-VIN compatibility, controlled 880 μs rise time to limit inrush, active-low ON pin logic, and CSP-8 footprint constraints in space-constrained mobile designs.
Technical Context
The PI3PD22919GBEX implements an integrated charge pump to fully enhance the internal N-channel MOSFET across its full 0.75–3.6 V input range, enabling stable low RON without external gate drive. Its active-low ON control interface directly interfaces with baseband processors and PMIC GPIOs.
It features internally regulated slew rate control (880 μs typical VOUT rise time at 3.6 V), a dedicated 1250 Ω on-die pulldown for rapid VOUT discharge upon disable, and guaranteed operation from –40°C to +85°C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.75 V to 3.6 V - supports single-cell Li-ion, LDO outputs, and low-voltage SoC I/O rails. |
| Max Continuous Current | 4 A - enables direct switching of high-current peripherals like displays or USB ports. |
| RON (Typ/Max) | 7.1 mΩ / 9.8 mΩ at 3.6 V - minimizes voltage drop and power loss in battery-sensitive paths. |
| VOUT Rise Time | 880 μs at 3.6 V - limits inrush current to protect upstream capacitors and source regulators. |
| Shutdown Current | 5.5 μA max - preserves battery life during system sleep modes. |
| Output Discharge Resistor | 1250 Ω - ensures VOUT falls rapidly to near-GND within microseconds after disable. |
| ESD Rating (HBM) | 4000 V - meets JEDEC Class II requirements for handheld device front-end robustness. |
Pinout & Package
Package: 8-ball Chip Scale Package (CSP), 0.95 mm × 1.95 mm, 0.5 mm pitch, Pb-free and RoHS-compliant (GB code).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Ball D1) | Power Ground Reference | Primary return path for switch current and internal circuitry; must be low-impedance. |
| ON (Ball D2) | Active-Low Enable Input | Drives internal control logic; requires pull-up or processor GPIO; floating not allowed. |
| VOUT (Balls A1, B1, C1) | Switch Output Terminal | Three parallel balls reduce trace resistance and thermal impedance for 4-A load delivery. |
| VIN (Balls A2, B2, C2) | Switch Input Terminal | Three parallel balls minimize input path resistance; requires local 1-μF ceramic bypass capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RON with charge pump | Enables <10 mΩ conduction across full 0.75–3.6 V range without external gate bias. |
| Controlled turn-on slew rate | Fixed 880 μs VOUT rise time eliminates need for external RC timing components. |
| Integrated quick output discharge | 1250 Ω on-die pulldown discharges VOUT in <10 μs - avoids floating or leakage-induced wakeups. |
| Low-threshold ON input | Accepts logic-high as low as 0.9 V at 0.75 V VIN, compatible with sub-1-V I/O standards. |
| Ultra-small CSP-8 footprint | 0.95 mm × 1.95 mm area saves >60% board space vs. comparable SOT-23 or WDFN packages. |

FAQ
What is the minimum input voltage supported by the PI3PD22919GBEX?
The PI3PD22919GBEX supports a minimum input voltage of 0.75 V, verified per datasheet Recommended Operating Conditions and confirmed across –40°C to +85°C ambient temperature. This allows direct integration with buck-boost regulators operating near end-of-battery discharge, unlike most load switches requiring ≥1.0 V.
Does the PI3PD22919GBEX require an external pull-up resistor on the ON pin?
Yes - the ON pin is active-low and must not be left floating. A pull-up resistor (typically 10–100 kΩ to VIN) is required to ensure defined logic-high state during power-up and reset. The datasheet specifies maximum ON input leakage current as 0.1 μA, confirming minimal loading on the driving GPIO.
Can the PI3PD22919GBEX be used with input capacitors larger than 1 μF?
Yes - the datasheet recommends ≥1 μF ceramic input capacitance but confirms stable operation with larger values, including 47 μF shown in application waveforms. Larger CIN improves input ripple suppression but does not affect turn-on timing, which is internally controlled.
Is there a replacement part for the discontinued PI3PD22919GBEX?
No direct replacement is offered by Diodes Incorporated. The datasheet explicitly states "DISTCONTINUED - NO ALTERNATIVE PART NUMBERS". Customers requiring new designs should evaluate Diodes' AP21xx series or AP22xx series load switches, which offer similar low-voltage operation and CSP packaging but differ in RON, timing, and feature set.
