Product details
Overview
MC22XSD200BEK from NXP Semiconductors is a dual 24 V high-side switch IC with two independently controlled 22 mΩ (at 25 °C) SMARTMOS power switches, 3.0 A steady-state current per channel, 16-bit SPI interface up to 8.0 MHz, and integrated overcurrent/overtemperature/open-load diagnostics. It serves as a protected load driver in industrial control modules for solenoids, bulbs, and DC motors.
For engineers reviewing the MC22XSD200BEK datasheet, MC22XSD200BEK pinout, MC22XSD200BEK application, or MC22XSD200BEK equivalent, key selection criteria include programmable slew rates for EMC compliance, dynamic overcurrent threshold profiling, autonomous operation via internal PWM clock, and Fail-safe mode retention of controllability during SPI communication loss.
Technical Context
The MC22XSD200BEK implements dual independent high-side switching channels using SMARTMOS technology, each featuring individually configurable slew rate (high/medium/low), selectable overcurrent detection profiles (bulb vs. DC motor), and real-time current sensing via CSNS pin with two programmable ratios (1/1500 or 1/500). Internal gate drivers support VPWR range from 6.0 V to 58 V.
Control is executed through a 16-bit SPI interface operating at up to 8.0 MHz, with dedicated pins for chip select (CSB), clock (SCLK), serial input (SI), and serial output (SO). Fault handling includes latchable overtemperature shutdown at 175 °C typical, severe short-circuit detection down to 30 cm wiring length (high slew), and open-load detection in both ON and OFF states - including LED loads at 7.0 mA typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) @ 25 °C | 22 mΩ max per channel - enables low conduction loss and <3.0 A continuous current drive without external heatsinking on standard PCBs |
| VPWR Range | 8.0–36 V full spec / 6.0–58 V extended - supports wide industrial supply rails including battery transients and brownout conditions |
| SPI Interface | 16-bit, up to 8.0 MHz - allows fast configuration and diagnostic readback compatible with 3.3 V and 5.0 V microcontrollers |
| Overcurrent Thresholds | Configurable from 1.4 A to 38.5 A (CSR0) or 0.48 A to 12.8 A (CSR1) - adapts protection sensitivity to bulb inrush or motor stall behavior |
| Open-Load Detection | 7.0 mA typ. in ON state - reliably identifies disconnected LEDs or high-impedance loads without false triggers |
| Thermal Shutdown | 175 °C typical junction temperature - prevents thermal runaway while allowing safe operation up to 125 °C ambient |
| Fail-Safe Mode | Autonomous operation retained after SPI loss - maintains configured outputs and fault reporting via FSB/FSOB pins |
Pinout & Package
MC22XSD200BEK uses a 32-pin SOIC-EP (exposed pad) package measuring 10 mm × 11 mm, with thermal resistance RθJC = 1.4 °C/W - optimized for industrial board layouts requiring robust thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLOCK | PWM timing reference input | Enables external clock synchronization or internal autonomous PWM generation; internal pull-down ensures defined state at power-up |
| HS0 / HS1 | High-side power switch outputs | Drain terminals of dual MOSFETs; connect directly to loads; rated for 58 V VPWR and -32 V reverse transient |
| CSNS | Current/temperature sense analog output | Provides proportional current (CSR0/CSR1 selectable) or GND-pin temperature voltage; requires external pull-down resistor |
| IN0 / IN1 | Direct digital control inputs | Enable hardware-level override of SPI control; internal pull-down ensures OFF default; tolerate VPWR-referenced logic up to 58 V |
| CONF0 / CONF1 | Overcurrent profile configuration | Select bulb (fast trip) or DC motor (latched, delayed) response per channel; require external GND pull-down resistors (1–50 kΩ) |
| FSB / FSOB | Active-low fault status outputs | FSB signals general fault condition; FSOB asserts only in Fail-safe mode; both are open-drain and require external VDD/VPWR pull-ups |
| VPWR | Main power supply input | Exposed pad connection to positive rail; serves as drain node for both switches; critical for thermal performance and current path integrity |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side switches | Each channel fully isolated with separate diagnostics, slew control, and overcurrent profiles - eliminates cross-talk in multi-load systems |
| Programmable slew rate (3 settings) | Reduces EMI emissions by limiting dV/dt during switching - selectable per channel to match load type (e.g., high slew for motors, low for LEDs) |
| Dynamic overcurrent threshold | Adapts trip point during inrush to avoid nuisance shutdown while maintaining accurate stall detection - essential for incandescent bulb and motor startup |
| Open-load detection in ON/OFF states | Verifies load continuity before and after activation - enables predictive maintenance and prevents undetected open-circuit failures in safety-critical systems |
| Fail-safe operational mode | Maintains last-known output state and continues fault monitoring without SPI - ensures deterministic behavior during host MCU reset or bus interruption |
Applications
| Industrial PLC Output Module | Automated Test Equipment (ATE) |

FAQ
What is the maximum continuous current rating per channel for the MC22XSD200BEK?
The MC22XSD200BEK supports up to 3.0 A steady-state current per channel, validated under conditions where the maximum junction temperature is not exceeded. Thermal design must account for package RθJA = 22 °C/W and board-level heatsinking to sustain this rating continuously in ambient temperatures up to 125 °C.
Does the MC22XSD200BEK support open-load detection for LED loads?
Yes, the MC22XSD200BEK provides open-load detection in both ON and OFF states, with a typical threshold of 7.0 mA in ON state - specifically designed to detect disconnected or failed LED strings without false positives caused by leakage currents.
How does the MC22XSD200BEK handle communication loss with the host microcontroller?
When SPI communication is lost, the MC22XSD200BEK automatically enters Fail-safe mode - retaining its last configured output states, continuing autonomous monitoring, and asserting the FSOB pin to signal the condition. This ensures deterministic behavior without requiring host intervention.
Can the slew rate be configured independently for each channel of the MC22XSD200BEK?
Yes, the MC22XSD200BEK supports individually programmable slew rates (high/medium/low) per channel via SPI register settings. This allows optimization for mixed-load systems - e.g., fast switching for motors and slower edges for EMI-sensitive LED circuits - without hardware changes.
What is the purpose of the CONF0 and CONF1 pins on the MC22XSD200BEK?
The CONF0 and CONF1 pins configure the overcurrent detection profile for each channel - selecting between bulb (fast-trip, inrush-tolerant) and DC motor (latched, delayed) response modes. They require external pull-down resistors (1–50 kΩ) and are sampled at power-up or reset to set fault-handling behavior.
