Key Features

• 4x Independent Channels: Control multiple loads with individual N-Channel outputs
• Wide Load Voltage Range: 10.8V to 35V operation
• Integrated Protection: Fixed current limiting (100mA max), over-temperature, and over-voltage fault protection
• Status Monitoring: Built-in status flag for real-time fault detection
• Industrial Temperature Range: -25°C to +125°C junction temperature (T_J)
• Non-Inverting Inputs: Simplified logic interface with On/Off control

Technical Specifications

This surface-mount power management IC features a 20-SOIC package (7.50mm width) with four general-purpose switches in a 1:1 input/output ratio. Requires no separate V_CC/V_DD supply voltage, reducing design complexity. The non-inverting On/Off interface ensures straightforward integration into existing control systems while status flag functionality provides immediate diagnostic feedback.

Typical Applications

• Industrial automation control systems
• Automotive electronic control units (ECUs)
• Power distribution modules in robotics
• Load switching in HVAC controls
• Protection circuits for sensors and actuators

About Power Distribution Switches

Power distribution switches are essential integrated circuits that manage electrical load control in complex electronic systems. They provide safe, localized switching capabilities while protecting downstream components from voltage spikes, current surges, and thermal overloads.

Modern PMIC switches like this 4-channel device simplify circuit board design by replacing discrete components. Their integrated protection features reduce system failure rates in industrial machinery, automotive subsystems, and smart appliances—where controlled power sequencing and fault resilience are critical.

Packaging

Supplied in protective tube packaging for secure transit and ESD safety. Compatible with standard automated pick-and-place assembly equipment.

Frequently Asked Questions

Q: Does this IC require external current-limiting resistors?
A: No—it features built-in fixed current limiting at 100mA per channel.

Q: Is the status flag output active-high or active-low?
A: The open-drain status flag pulls low during fault conditions (over-current, over-temperature, or over-voltage).

Q: Can I parallel channels for higher current capacity?
A: No—channels operate independently. Paralleling isn’t recommended due to potential current imbalance.

Q: What’s the difference between power switches and standard MOSFETs?
A: Power switches integrate control logic, protection circuits, and diagnostics—unlike discrete MOSFETs requiring external components.

Q: Does PCX provide design support for this component?
A: Yes! Our engineering team offers application guidance. Download datasheet for integration details.

Q: Are these suitable for 24V industrial systems?
A: Absolutely. The 10.8V–35V range covers 12V/24V automotive and industrial voltage standards.
