E-Fuse MX5069 High-Side N_FET Driver Efficiently Manage Power Distribution For 24V And 48V Industrial Systems

MX5069 EFuse IC High Side N_FET Driver Power Distribution For 24V 48V Industrial Systems

The MX5069 high-side N_FET driver works with an external MOSFET and acts as an ideal diode rectifier when connected in series with the power supply. This controller enables MOSFETs to replace diode rectifiers in power distribution networks,reducing power loss and voltage drop. The MX5069 controller provides charge pump gate drive for an external N- channel MOSFET and fast response comparator to turnoff the FET when current flows in reverse.The current limit in the external series pass N-Channel.MOSFET are programmable. The input undervoltage and overvoltage lockout levels are programmabled by resistance divider networks. The MX5069 automatically restarts at a fixed duty cycle. MX5069 is available in 10-pin DFN3*3 and MSOP10Lpackage.

MX5069 EFuse IC High Side N_FET Driver Power Distribution For 24V 48V Industrial Systems

PIN NO. PIN name Description
MSOP 10 DFN3*3
1 10 SENSE Current sense input: The voltage across the current sense resistor (RS) is measured from VIN to this pin.
2 9 VIN Positive supply input: A small ceramic bypass capacitor close to this pin is recommended to suppress transients which occur when the load current is switched off.
3 1 UVLO/EN

This is a dual function control pin. When used as an ENABLE pin and pulled down, it shuts off the internal pass MOSFET.

As an UVLOpin, it can be used to program different UVLO trip point via external resistor divider.
4 2 OVP Overvoltage lockout: An external resistor divider from the system input voltage sets the overvoltage turnoff threshold. The disabled threshold at the pin is 1.23V.
5 8 GND Circuit ground
6 3 SST A capacitor from this pinto GND sets output voltage slew rate.
7 4 ILIM Current limit set: An external resistor connected to this pin, combined with a current detection resistor to achieve overcurrent protection.
8 5 PGD Power Good indicator: An open drain output.
9 7 OUT Output feedback: Connect to the output rail (external MOSFET source).
10 6 GATE Gate drive output: Connect to the external MOSFET’s gate. This pin's voltage is typically 12V above the OUT pin when enabled.
