CLTM12-Series Solid State Load Controller PROD UC T W E BP A GE request sample, configure part, watch video The CLTM12-S is a compact, solid state load controller with 12 high-side outputs, 4 digital inputs, 3 discrete inputs, 2 address lines, and a CAN baud rate select line. It provides fast, low-loss, solid state on/off switching along with short circuit protection for each output, as well as load status and power diagnostics. Relative to electromechanical relays, the CLTM12 electronic control module increases thermal efficiency by providing lower power dissipation and higher power-to-weight densities. Typical Applications ∙ On/Off-Highway ∙ Directional and Hazard Signals ∙ Beacon and Alarm Systems IP69K Sealing When Connected ∙ Site and Work Lights

Configuration Digital inputs The digital inputs (IND_1, IND_2, IND_3. IND_4_WKE) sense the presence of three voltage level states: “Active High”, “Open” and “Active Low” and are compatible with standard 5v logic devices (E.g. when the input is at +5v it will be read as a logic ‘1’ or “High”. When the input is at 0v or GND it will be read as logic ‘0’ or “Low”.) The unused digital inputs can be left disconnected. • Absolute limits -2.3 to 36V • Input resistance: 1K Ohm • Input pin voltage open circuit: 2.75V Thresholds Low = 0 to 1.08V Open = 1.58 to 4.28V High = 4.78V to 6.63V These...

Configuration Discrete Input Impedance Model Address and Baud Rate select inputs The address lines (ADD_1, ADD_2 and baud rate select) are active Low inputs that the software uses to identify the application based on the configuration of the wiring harness. These pins recognize two states Low and High. Address 1 Open circuit voltage = 3.3V Input resistance > 50K Ohms Low = below 0.72V High = above 1.65V Baud Rate Select input No connect (J1-3) for 250 Kbits/second select. Connect (J1-3 to J1-15) for 500 Kbits/second select. If the CLTM12-S-Series is configured for 500k Baud operation,...

Address & Baud Rate select Input Impedance Model Output Channels The 12 High side output channels are switched with MOSFETs connected in a back-to-back arrangement so that back-feeding is not possible when the channel is turned off. 5A The total current supplied by the CLTM12-S is limited to 75A. All channels employ the following: • Load Presence Detection • Latched shutdown overcurrent detection with reset. • Overcurrent surge allowance that prevents overcurrent latch tripping when starting high surge loads such as incandescent lamps. Output Channel Schematic

Output Channel Schematic (continued) When a channel is off, a current source supplies 1.15 mA to the load so that the channel output voltage can be used to determine its status. The real-time monitoring functions for the faults: “Open circuit” and “ON when commanded OFF” are implemented by comparing channel voltage to input voltage. “Open circuit” is asserted when the channel is OFF and the difference between the Input voltage and the Channel voltage is between 1.5V and 6.0 volts. If the difference between the Input and Channel voltages is between 0 and 1.5V when the channel is OFF, the “ON...
