Product details
Overview
MIC94052BC6-TR from Micrel is a P-channel MOSFET high-side load switch in SC-70-6 package, featuring 70mΩ typical RDS(ON) at VGS = –4.5V, 2A continuous drain current, and 1.8V to 5.5V input voltage range - optimized for space-constrained Li-ion portable power rails.
For engineers reviewing the MIC94052BC6-TR datasheet, MIC94052BC6-TR pinout, MIC94052BC6-TR application, or MIC94052BC6-TR equivalent, key selection criteria include verified RDS(ON) vs. VGS performance down to 1.8V, –40°C to +150°C junction temperature capability, and SC-70-6 thermal resistance (θJA = 240°C/W) for compact battery-powered designs.
Technical Context
This device operates as a single N-channel gate-controlled high-side switch with no integrated pull-up resistor (unlike MIC94053), requiring external gate drive control. Its static threshold voltage (VGS(th)) ranges from –0.5V to –1.2V, enabling reliable turn-on at low supply voltages.
Designed for sub-5V load switching, it supports pulsed drain currents up to ±6A and exhibits normalized RDS(ON) variation under temperature stress - maintaining ≤1.3× nominal value across –40°C to +150°C at VGS = –4.5V and ID = –1.8A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | –6V maximum - supports safe operation with 5.5V input rails plus transient margin |
| RDS(ON) (typ) | 70mΩ at VGS = –4.5V - enables <140mW conduction loss at 2A load current |
| ID Continuous | ±2A at TA = 25°C - sufficient for USB-powered peripherals and display backlight loads |
| VGS Range | 1.8V to 5.5V - compatible with Li-ion (3.0–4.2V), LDO outputs, and logic-level microcontrollers |
| Junction Temp | –40°C to +150°C - qualified for industrial and extended-temperature portable environments |
| θJA | 240°C/W - requires minimal PCB copper area for thermal management in SC-70-6 footprint |
Pinout & Package
SC-70-6 (C6) package: 2.20mm × 1.35mm × 0.95mm body, 0.65mm pitch, 6-pin surface-mount with exposed drain pad (pins 1,2,5,6 tied internally to drain).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Drain (D) | All four pins connect to internal drain node - must be shorted externally to minimize RDS(ON) and thermal resistance |
| 3 | Gate (G) | Control terminal accepting negative VGS; no internal pull-up - requires active driver or external resistor |
| 4 | Source (S) | Reference terminal tied to system ground or load return path; defines VGS polarity |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage gate drive | Operates with VGS as low as –1.8V - enables direct interface with 1.8V/2.5V logic without level-shifting |
| High-current density | 2A continuous rating in SC-70-6 - delivers >0.9A/mm² current density for ultra-compact layout |
| Thermal robustness | 150°C max junction temperature - supports operation in sealed enclosures without forced airflow |
| Fast switching | 60ns turn-off delay + 20ns fall time - reduces transition losses in PWM-controlled loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the gate threshold voltage range for MIC94052BC6-TR?
The MIC94052BC6-TR has a gate threshold voltage (VGS(th)) ranging from –0.5V to –1.2V at ID = –250µA. This low threshold enables reliable turn-on with 1.8V logic-level gate drive, critical for battery-powered systems where supply voltage may sag below 2.5V. The MIC94052BC6-TR does not include an internal gate pull-up resistor, so external control is required to ensure defined state during power-up.
Does MIC94052BC6-TR include an internal gate pull-up resistor?
No, the MIC94052BC6-TR does not include an internal gate pull-up resistor. That feature is exclusive to the MIC94053 variant. The MIC94052BC6-TR requires active gate control - either via a dedicated driver or an external pull-down/pull-up network - to define its default OFF state. This gives designers full flexibility in sequencing but adds one external component versus the MIC94053BC6-TR.
What is the maximum continuous drain current for MIC94052BC6-TR at 85°C ambient?
The MIC94052BC6-TR supports ±1.4A continuous drain current at TA = 85°C when mounted on a 1-inch² pad of 2 oz. copper. This derating from the 2A rating at 25°C reflects thermal limitations of the SC-70-6 package. The MIC94052BC6-TR's θJA of 240°C/W means junction temperature rises ~336°C above ambient at 1.4A - confirming the need for proper PCB copper pour to stay within the –40°C to +150°C junction limit.
Can MIC94052BC6-TR be used in Li-ion battery applications?
Yes, the MIC94052BC6-TR is explicitly designed for Li-ion applications, supporting input voltages from 1.8V to 5.5V - covering full Li-ion cell range (2.7–4.2V) plus margin for charging circuits and regulators. Its –40°C to +150°C junction temperature range and low 70mΩ RDS(ON) at 4.5V make the MIC94052BC6-TR ideal for protecting battery-fed rails in smartphones, tablets, and wearables without significant voltage drop or thermal penalty.
What is the recommended PCB layout practice for MIC94052BC6-TR's drain pins?
All four drain pins (1, 2, 5, 6) of the MIC94052BC6-TR must be connected together on the PCB using wide, low-impedance copper traces. This is mandatory to achieve the specified 70mΩ RDS(ON) - isolating any drain pin increases resistance and localized heating. The MIC94052BC6-TR datasheet emphasizes that unconnected drain pins degrade both conduction efficiency and thermal dissipation, especially under 2A loads.
