Product details
Overview
AP22916DCA4-7 from Diodes Incorporated is a single-channel, P-channel ultra-low leakage load switch optimized for battery-powered portable electronics. It operates from 1.3V to 5.5V input, delivers up to 2A continuous load current, features 60mΩ typical RDS(ON) at 5V, and integrates True Reverse Current Blocking (TRCB) with 25mV trigger threshold and 10μs response time. It is used in smartphone power rail sequencing to isolate auxiliary peripherals during sleep mode.
For engineers reviewing the AP22916DCA4-7 datasheet, AP22916DCA4-7 pinout, AP22916DCA4-7 application, or AP22916DCA4-7 equivalent, key selection criteria include its fast turn-on time (85μs at 5V), absence of output discharge circuitry (distinguishing it from AP22916B/C), active-high enable logic with 1.0V VIH minimum, and ultra-low 0.5μA quiescent current for standby power integrity.
Technical Context
The AP22916DCA4-7 implements a P-channel MOSFET-based load switch with integrated smart pull-down on the ON pin and TRCB protection that activates when VOUT exceeds VIN by ≥25mV. Its control logic ensures immediate gate disconnection upon overvoltage detection, preventing reverse current flow even when disabled.
Unlike versions B and C, the AP22916D variant omits the internal VOUT discharge resistor - eliminating automatic capacitor bleed during shutdown - and provides faster switching: tON = 85μs and tR = 50μs at 5V input, with slew rate of 90mV/μs. It maintains full 2A current capability across the −40°C to +85°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.3V–5.5V: supports direct interface with 1.3V, 1.8V, 2.5V, 3.6V, and 5V system rails without level shifting. |
| RDS(ON) @ 5V | 54mΩ typical: enables ≤107mV forward drop at 2A, minimizing conduction loss and thermal rise. |
| Quiescent Current | 0.5μA typical: reduces battery drain in always-on subsystems such as real-time clocks or sensor wake-up circuits. |
| TRCB Trigger Threshold | 25mV: detects minimal reverse voltage margin to block leakage before battery backfeed occurs. |
| tON @ 5V | 85μs typical: allows rapid power-up of USB peripherals or display modules without violating system timing budgets. |
| VIH (ON Pin) | 1.0V minimum: compatible with 1.2V/1.8V GPIOs without external level translation. |
| Operating Temperature | −40°C to +85°C: qualified for consumer and industrial portable equipment environments. |
Pinout & Package
AP22916DCA4-7 is housed in a wafer-level chip-scale U-WLB0808-4 (Type B) package: 0.78mm × 0.78mm × 0.455mm, 0.4mm ball pitch, with backside laminate. The four-ball layout supports high-density PCB integration in space-constrained mobile designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (A1) | Switch output / P-MOSFET drain | Connects to load; requires local 0.1µF–1µF bypass capacitor to ground for transient stability. |
| VIN (A2) | Power input / P-MOSFET source | Connects to supply rail; requires 1µF ceramic decoupling capacitor placed adjacent to pin. |
| GND (B1) | Reference ground | Low-impedance return path for both input and output currents; must be tied to system ground plane. |
| ON (B2) | Active-high enable control | Drives internal gate driver; internal 750kΩ pull-down ensures safe OFF-state default if left floating. |
Key Features
| Feature | Design Value |
|---|---|
| True Reverse Current Blocking (TRCB) | Blocks reverse current within 10μs when VOUT > VIN + 25mV - prevents battery backfeed in multi-rail systems. |
| No Output Discharge Resistor | Eliminates automatic VOUT capacitor discharge during disable - preserves state in memory-backed or configuration-sensitive loads. |
| Ultra-Low IQ | 0.5μA typical supply current - extends battery life in always-on monitoring functions (e.g., lid-open detection, ambient light sensing). |
| Wide Input Compatibility | 1.3V–5.5V operation enables use across legacy and modern low-voltage SoC domains without external regulators. |
| ESD Robustness | 2kV HBM / 1kV CDM rating - withstands handling and board assembly stresses without additional protection circuitry. |
Applications
| Smartphone Peripheral Isolation | Wearable Sensor Power Gating |
|---|---|
|
Use Scenario: Isolating camera module or NFC transceiver during phone sleep mode to prevent standby current leakage. IC Role / Device Role / Timing Role: Load switch controlling VOUT rail; activated only during active imaging/NFC sessions with precise 85μs turn-on timing.

Use Scenario: Enabling/disabling ECG or SpO₂ analog front-end during intermittent measurement cycles in fitness trackers. IC Role / Device Role / Timing Role: Power gate for sensor biasing circuitry; synchronized to MCU wake-up interrupt with <100μs latency. Use Value: Limits sensor-related quiescent draw to <0.5μA between measurements, enabling multi-day operation on coin-cell batteries. |
| USB-C Accessory Detection | Portable Medical Device Rail Sequencing |
|
Use Scenario: Controlling power to USB-C CC logic and VCONN circuitry only when cable insertion is confirmed. IC Role / Device Role / Timing Role: Controlled power switch for VCONN supply; enabled after CC line handshake completes. Use Value: Prevents unnecessary 1W+ VCONN dissipation during idle periods, meeting USB-IF power budget constraints for portable hosts. |
Use Scenario: Sequencing power to ADC reference and op-amp signal chain in handheld glucose meters prior to measurement. IC Role / Device Role / Timing Role: Precision-controlled rail enable with fast rise time (50μs) to meet medical-grade signal settling requirements. Use Value: Ensures stable analog biasing before sampling, eliminating offset drift caused by slow-ramping supplies in critical diagnostic readings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar load-switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP22916BCA4-7 | Includes internal VOUT discharge resistor (150Ω); slower tON (1400μs typ. at 5V); same TRCB and voltage range. | Required where automatic VOUT discharge is needed to reset downstream logic or prevent latch-up. | Select when downstream circuitry lacks independent discharge path and relies on switch-integrated bleed. |
| TPL7407LDR | 7-channel N-MOSFET array; 1.8V–5.5V; no TRCB; higher RDS(ON) (300mΩ min); 2.5mA IQ. | Suitable for multi-load parallel control but not for reverse-current-critical single-rail isolation. | Choose only for non-reverse-sensitive, multi-output fanout where cost-per-channel outweighs leakage and protection needs. |
Compared with AP22916BCA4-7, the AP22916DCA4-7 trades automatic discharge for faster switching and lower leakage - ideal for state-retentive, low-IQ applications. Versus TPL7407LDR, it offers superior TRCB protection, 50× lower IQ, and 5× lower RDS(ON), making it optimal for precision single-rail isolation.

FAQ
Does AP22916DCA4-7 provide output discharge functionality?
No. The AP22916D variant explicitly omits the internal VOUT discharge resistor present in AP22916B/C versions. When disabled, VOUT remains floating unless an external bleed path is provided. This preserves charge on output capacitors and maintains state in downstream circuits like SRAM or configuration latches.
What is the maximum continuous current rating under worst-case thermal conditions?
The AP22916DCA4-7 is rated for 2A continuous current across −40°C to +85°C ambient, verified with RθJA = 195°C/W and maximum junction temperature of +125°C. At 2A and 5V input, power dissipation remains ≤212mW (2A² × 60mΩ), well below the 510mW absolute max, ensuring reliable operation without forced cooling.
How does True Reverse Current Blocking (TRCB) behave when the ON pin is low?
TRCB remains fully active regardless of ON pin state. If VOUT exceeds VIN by ≥25mV - for example, due to back-driving from a charged load capacitor or cross-coupled rail - the internal comparator triggers within 10μs to disconnect the P-MOSFET channel, blocking reverse current flow even in the disabled state.
Can AP22916DCA4-7 operate reliably at 1.3V input with 2A load?
Yes. At 1.3V input, RDS(ON) rises to 280mΩ typical (320mΩ max over temperature), resulting in ≤560mV drop at 2A. This remains within the 1.3V system's valid output window (≥0.7V for most 1.3V logic), and thermal rise stays within limits given the device's 195°C/W θJA and 510mW power rating.
