Product details
Overview
MIC94053BC6-TR from Micrel is a P-channel MOSFET load switch with integrated gate pull-up resistor, designed for high-side switching in space-constrained portable systems. It delivers 70mΩ typical RDS(ON) at VGS = –4.5V, supports 1.8V–5.5V input range, handles ±2A continuous drain current, and operates across –40°C to +150°C junction temperature - enabling use in Li-ion-powered barcode scanners and MP3 players.
For engineers reviewing the MIC94053BC6-TR datasheet, MIC94053BC6-TR pinout, MIC94053BC6-TR application, or MIC94053BC6-TR equivalent, key selection criteria include verified gate pull-up functionality, SC-70-6 package thermal performance (θJA = 240°C/W), RDS(ON) vs. VGS behavior down to –1.8V, and confirmed high-side switch timing (td(off) = 60ns).
Technical Context
The MIC94053BC6-TR integrates a 250–550kΩ internal gate-to-source pull-up resistor, ensuring default-OFF operation until actively pulled low - eliminating external bias components. Its P-channel architecture enables simple high-side load control without level-shifting circuitry.
It operates over 1.8V–5.5V supply range with guaranteed RDS(ON) ≤ 84mΩ (max) at –4.5V VGS, and exhibits normalized on-resistance drift of <15% across –40°C to +125°C per characterization curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VGS Range | 1.8V to 5.5V - supports direct interface with 1.8V/2.5V/3.3V/5V logic and Li-ion battery rails. |
| RDS(ON) (typ) | 70mΩ at VGS = –4.5V - limits I²R loss to ≤70mW at 1A, critical for thermally constrained SC-70-6 layout. |
| RDS(ON) (max) | 84mΩ at VGS = –4.5V - defines worst-case conduction loss under production tolerance and temperature. |
| ID (cont) | ±2A at TA = 25°C - sets maximum steady-state load current before derating due to package power dissipation (270mW @ 85°C). |
| td(off) | 60ns - determines minimum off-time in PWM-controlled load switching applications. |
| TJ Range | –40°C to +150°C - qualifies for industrial and extended-temperature portable equipment deployment. |
Pinout & Package
Package: Teeny™ SC-70-6 (C6), 2.20mm × 1.35mm footprint, 0.65mm pitch, 0.95mm max height - optimized for ultra-dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Drain (D) | All four pins are internally connected to the MOSFET drain; must be externally shorted to minimize RDS(ON) and thermal resistance. |
| 3 | Gate (G) | Control terminal; internal pull-up resistor connects to source, requiring active low drive to turn ON the device. |
| 4 | Source (S) | Reference node for gate control and current return path; tied to system VIN in high-side configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated gate pull-up resistor | 250–550kΩ ensures fail-safe OFF state without external components, reducing BOM count and board area. |
| Low-voltage operation | Functional down to 1.8V VGS, enabling compatibility with modern low-power microcontrollers and battery voltage sag conditions. |
| High-current capability | ±2A continuous rating at 25°C ambient supports USB-powered peripherals and display backlight loads. |
| Thermal robustness | 150°C max junction temperature and 240°C/W θJA allow sustained operation in sealed handheld enclosures. |

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 |
|---|---|---|---|
| TPS22967DSGR | No internal pull-up; requires external gate resistor network for default-OFF behavior. | Lacks integrated pull-up, increasing component count and layout complexity in space-sensitive designs. | Select when precise gate threshold tuning or higher 6V VDS rating is required. |
| AP2311GN | Higher RDS(ON) (120mΩ typ @ –4.5V); no integrated pull-up; SOT-23-6 package (larger footprint). | Requires external pull-up and occupies ~2.5× more PCB area than SC-70-6. | Choose only if SC-70-6 assembly capability is unavailable or higher surge current rating is needed. |
Compared with TPS22967DSGR and AP2311GN, the MIC94053BC6-TR uniquely combines verified internal gate pull-up, 70mΩ RDS(ON), and SC-70-6 size - delivering lowest component count and smallest footprint for default-OFF high-side switching in sub-5V portable systems.

FAQ
What is the function of the internal gate pull-up resistor in MIC94053BC6-TR?
The internal gate pull-up resistor (250–550kΩ) in MIC94053BC6-TR ensures the P-channel MOSFET remains OFF until the gate is actively pulled low by a controller. This fail-safe behavior eliminates the need for an external pull-up component, reducing BOM cost and PCB area. The resistor connects between gate and source, making MIC94053BC6-TR ideal for systems where default power-off is mandatory during reset or MCU initialization.
Does MIC94053BC6-TR support 1.8V logic-level control?
Yes, MIC94053BC6-TR operates with gate-to-source voltages as low as –1.8V, delivering RDS(ON) ≤ 180mΩ at that level. This enables direct interfacing with 1.8V GPIO outputs without level shifters. Verified performance down to –1.8V VGS makes MIC94053BC6-TR suitable for modern ultra-low-power microcontrollers and battery-voltage-sag scenarios in portable devices.
What is the maximum continuous current rating for MIC94053BC6-TR?
MIC94053BC6-TR supports ±2A continuous drain current at TA = 25°C, derating to ±1.4A at TA = 85°C due to its SC-70-6 package's 270mW power dissipation limit. This rating assumes proper PCB copper pour (1 sq-in, 2 oz) per Micrel's test condition. Real-world current capability depends on layout thermal design and ambient temperature - always verify junction temperature using θJA = 240°C/W.
How does MIC94053BC6-TR differ from MIC94052BC6-TR?
MIC94053BC6-TR includes an internal gate pull-up resistor (250–550kΩ), while MIC94052BC6-TR does not. This makes MIC94053BC6-TR a default-OFF device requiring active low gate drive, whereas MIC94052BC6-TR needs external biasing for defined startup state. Both share identical RDS(ON), package, voltage range, and thermal specs - the pull-up is the sole functional distinction.
Is MIC94053BC6-TR suitable for high-side switching in Li-ion battery applications?
Yes, MIC94053BC6-TR is explicitly qualified for Li-ion battery applications, supporting 1.8V–5.5V input range and operating across –40°C to +150°C junction temperature. Its low RDS(ON) minimizes voltage drop and power loss during battery discharge, and the integrated pull-up ensures safe power-down during battery insertion/removal events. Micrel's datasheet cites Li-ion use cases including cellular phones and PDAs.
