MP5036 12V, 0.4A to 5A, Current Limit Switch with 15V Over-Voltage Clamp in TSOT23 Package DESCRIPTION FEATURES The MP5036 is a protection device designed to Wide 2.9V to 14V Continued Operating protect circuitry on the output from transients on Input Range the input. It also protects the input from 26V Absolute Maximum Transient Input undesired shorts and transients coming from Voltage the output. Fixed 15V Over-Voltage Clamp Threshold Fast Output OVP Response During start-up, the inrush current is limited by Integrated 43m Power FET limiting the slew rate at the output. The slew Adjustable Current Limit or Fixed Current rate is controlled by the DV/DT pin setting. Limit when floating ILIMIT pin The maximum load at the output is current- Soft Start Time Programmable through limited. The magnitude of the current limit is the DV/DT Pin controlled by an external resistor from ILIMIT to Fast Response for Hard Short Protection GND. There is a fixed 2.5A current limit when OCP Hiccup Protection floating the ILIMIT pin. Thermal Shutdown and Auto Retry The output voltage is limited by the output over- Available in TSOT23-6 Package voltage protection (OVP) function. APPLICATIONS The device is available in a TSOT23-6 HDD, SSD package.

TOP MARKING BDK: Product code of MP5036GJ Y: Year code PACKAGE REFERENCE TOP VIEW EN DV/DT SOURCE VIN ILIMIT GND TSOT23-6 PIN FUNCTIONS Pin Name Description Enable. Force EN high to enable the MP5036. Float EN or pull EN to ground to 1 EN disable the IC. For quick start-up, pull EN up to VIN through a 300k resistor. 2 SOURCE Source of the internal power MOSFET and output terminal of the IC. 3 GND System ground. Current limit set. Place a resistor between ILIMIT and ground to set the value of the 4 ILIMIT current limit. Float ILIMIT to achieve a 2.5A fixed current limit. Supply voltage. The MP5036 operates from a 2.9V to 14V input rail. A ceramic 5 VIN capacitor is required to decouple the input rail. Connect VIN using a wide PCB trace. 6 DV/DT DV/DT. Connect a capacitor from DV/DT to ground to set the DV/DT slew rate. MP5036 Rev. 1.0 www.MonolithicPower.com 2 10/15/2019 MPS Proprietary Information. Patent Protected.
