Product details
Overview
MP5090GC-Z from Monolithic Power Systems is a dual-channel, low-quiescent-current load switch IC with 2A per channel continuous current capability, 30mΩ RDS(ON) at 5V VCC, and operation across 0.5V–5.5V input voltage range. It integrates soft-start, output discharge, hiccup-mode current limiting, thermal shutdown, and reverse-current blocking-designed for power rail sequencing and protection in portable SSDs and tablet mainboards.
For engineers reviewing the MP5090GC-Z datasheet, MP5090GC-Z pinout, MP5090GC-Z application, or MP5090GC-Z equivalent, this device supports dual independent enable control (EN1/EN2), parallel-channel configuration for 4A total, and ultra-low 40µA quiescent current-critical for battery-powered system standby efficiency and hot-swap reliability.
Technical Context
The MP5090GC-Z implements two independent N-channel MOSFET load switches with integrated gate drivers, controlled via separate EN1/EN2 inputs. Each channel features programmable soft-start (30µs VOUT rise time), internal 2.5A current limit (typical), and fast short-circuit response (~200ns turn-off).
It operates with a dedicated 1.85V–5.5V VCC supply for control logic and supports reverse-current blocking when both enables are asserted. Thermal protection triggers at 155°C with 30°C hysteresis, and hiccup mode cycles 2ms on / 90ms off under sustained overload.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Current (per channel) | 2A - Sustained load delivery for SSD power rails or USB peripheral supplies without derating at +85°C ambient. |
| RDS(ON) (VCC = 5V) | 30mΩ - Minimizes conduction loss (<300mW at 2A), enabling compact thermal design in CSP package. |
| Quiescent Current | 40µA - Enables multi-week battery standby in always-on subsystems (e.g., touch controller or sensor hub). |
| Input Voltage Range (VIN) | 0.5V–5.5V - Supports direct connection to Li-ion cells (2.7–4.2V), LDO outputs, or USB VBUS without level-shifting. |
| Shutdown Current | <1µA - Eliminates leakage path when disabled, preserving battery charge during deep sleep modes. |
| Soft-Start Time | 30µs (10%–90%) - Limits inrush dI/dt to <67A/µs, preventing >5% backplane voltage droop during hot-plug events. |
| Thermal Shutdown Threshold | 155°C - Protects silicon integrity during sustained overload; 30°C hysteresis ensures stable recovery after cooling. |
Pinout & Package
MP5090GC-Z uses an 8-ball CSP package (1.05mm × 1.60mm, 0.4mm pitch) optimized for space-constrained mobile PCBs. The package features bottom-side solder balls with exposed thermal pad for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1 / IN2 | Channel 1 / Channel 2 input power pins | Accept 0.5–5.5V supply; support reverse-current blocking when paired with OUT1/OUT2 in bidirectional configuration. |
| OUT1 / OUT2 | Channel 1 / Channel 2 load output pins | Deliver regulated power to downstream loads; internally discharged via 50Ω resistor when EN or VCC is low. |
| EN1 / EN2 | Independent enable inputs | Logic-high (>1.2V) activates respective channel; hysteresis (200mV) prevents chatter near threshold during noisy rail transitions. |
| VCC | Control circuit supply | Must be ≥1.85V for UVLO release; powers gate driver and protection logic-decoupled with 1µF ceramic capacitor. |
| GND | Power and signal reference | Common return for all channels and control logic; requires low-impedance plane connection to minimize ground bounce during switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1/EN2 allow staggered power-up of SoC cores and peripherals-enabling precise sequencing without external timers. |
| Output discharge function | 50Ω internal pull-down discharges light loads (e.g., GPIO lines or I²C pull-ups) within 100µs after disable-preventing floating states. |
| Hiccup-mode overcurrent protection | 2ms on / 90ms off cycling limits average power dissipation during fault, avoiding thermal runaway while maintaining detectability. |
| Parallel-channel capability | IN1–IN2 and OUT1–OUT2 can be externally shorted to deliver 4A total (2×2A) with matched RDS(ON) and thermal sharing. |
| Reverse current blocking | Body diode orientation enables unidirectional current flow; when both ENs high, reverse current from OUT to IN is blocked below 100nA. |
Applications
| Solid-State Drive (SSD) Power Rail Control | Tablet Mainboard Subsystem Sequencing |

Use Value: Hiccup-mode protection sustains 2.5A overload for 2ms before cycling-allowing mechanical completion of scan before safe shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS22965DSGR | Single-channel, 4A rating, 17mΩ RDS(ON), no output discharge, 1.2V min VIN | Lacks dual independent control and reverse-blocking; requires two units for same functionality. | Select when higher single-rail current (4A) and lower RDS(ON) outweigh need for integration and discharge. |
| ON Semi NCP45561MUTBG | Dual-channel, 3A/3A, 12mΩ RDS(ON), 1.8V min VIN, no soft-start, 1.2µA IQ | Higher minimum input voltage excludes Li-ion direct connection; no inrush control limits hot-plug robustness. | Select for ultra-low IQ and higher current where input rail ≥1.8V and soft-start is handled externally. |
Compared with TPS22965DSGR and NCP45561MUTBG, MP5090GC-Z uniquely combines dual independent control, 0.5V input compatibility, integrated soft-start, and output discharge in a 1.6mm × 1.05mm CSP-making it optimal for space- and battery-life-constrained portable designs requiring full rail autonomy.

FAQ
What is the maximum allowable junction temperature for MP5090GC-Z?
The absolute maximum junction temperature is 150°C per Absolute Maximum Ratings table. Thermal shutdown activates at 155°C (with 30°C hysteresis), but continuous operation above 125°C requires derating per θJA = 170°C/W (CSP package) and proper PCB copper area. Operation beyond 125°C ambient is not recommended without thermal simulation.
Can MP5090GC-Z operate with VIN below 1.0V?
Yes-MP5090GC-Z supports input voltages as low as 0.5V, verified across –40°C to +125°C. This enables direct connection to partially discharged Li-ion cells (down to 2.7V) or low-dropout regulator outputs without level-shifting, unlike alternatives requiring ≥1.2V minimum VIN.
Does MP5090GC-Z require external capacitors on EN pins?
No external EN pin capacitors are required. EN1/EN2 have built-in 1MΩ pull-down resistance and 200mV hysteresis, making them noise-immune with standard PCB routing. However, a 100pF ceramic capacitor may be added locally if routed near high-dI/dt traces to suppress edge-induced glitches.
How does the output discharge function behave during VCC dropout?
The 50Ω internal discharge resistor activates whenever EN1/EN2 is low OR VCC falls below UVLO (1.7V). During VCC dropout, discharge remains active until VCC drops below 0.8V, ensuring complete VOUT ramp-down even during sudden supply failure-critical for I/O state retention.
Is parallel-channel operation supported between MP5090GC-Z and MP5090GQHT-Z?
No-parallel operation requires matched RDS(ON) and thermal characteristics. MP5090GC-Z (30mΩ, CSP) and MP5090GQHT-Z (20mΩ, TQFN) exhibit unequal current sharing and asymmetric thermal rise, risking overload on the lower-RDS(ON) device. Parallel use is only validated within same package variant.
What is the typical enable propagation delay from EN assertion to VOUT regulation?
The EN-to-VOUT turn-on delay is 30µs (typical), measured from EN rising edge (10%) to VOUT reaching 10% of final value. This includes internal UVLO release, gate drive charging, and soft-start ramp initiation-ensuring predictable timing for sequenced power-up in multi-rail systems.
Does MP5090GC-Z support I²C or other digital interfaces?
No-MP5090GC-Z is an analog load switch with only digital enable inputs (EN1/EN2) and passive power terminals. It lacks any serial interface, registers, or programmable settings; configuration is fixed at silicon level per datasheet specifications.
