The 150°C TJ ceiling gives headroom for self-heating in a compact 2x2 mm LLP package — but that exposed pad is not optional: you must solder it to a PCB thermal land and via array to the ground plane to keep the die cool at full 192 mA output. Without that thermal path, the part will hit thermal shutdown well before the electrical limit. ## Lifecycle and sourcing posture The LM4570LQX/NOPB carries an Active lifecycle status and is ROHS3 compliant. For BOM planning, this is a standard-shelf part that can be dual-sourced through independent distribution.","metaTitle":"LM4570LQX/NOPB Brushed DC Motor Driver, 192mA, 8-WQFN","metaDescription":"LM4570LQX/NOPB fully integrated brushed DC motor controller with Power MOSFET half-bridge, 192mA output, 2.4-5.5V supply, -40 to 150°C.

The 8-WQFN package includes an exposed thermal pad (listed as 8-LLP-EP). It must be soldered to a PCB land and connected to the ground plane for thermal management."},{"question":"What is the maximum current of LM4570LQX?","answer":"The continuous output current rating is 192 mA per half-bridge. Peak current may be higher for short durations, but the steady-state motor current must stay under this limit."},{"question":"Is LM4570LQX compatible with 3.3V logic?","answer":"Yes. The supply voltage range of 2.4 V to 5.5 V covers both 3.3 V and 5 V logic rails. The parallel control inputs are referenced to the supply voltage, so a 3.3 V microcontroller can drive the direction and brake pins directly when VCC is set to 3.3 V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4570LQX-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4570LQX-NOPB when reusing this data.
