HEXABITZ Moudule SPST 12V/20A MOSFET Switch

Description
H0FR7 is a Single Pole Single Throw (SPST) 12V/20A MOSFET Switch module, based on STMicroelectronics STD36P4LLF6 MOSFET P transistor, bi-directional current sense amplifier INA199A2DCKT, and STM32F0 MCU.

The switch is SPST (Single Pole Single Throw) type STD36P4LLF6 :
This device is a P-channel Power MOSFET developed using the STripFET™ F6 technology, with a new trench gate structure. The resulting Power MOSFET exhibits very low RDS(on) in all packages.
The voltage-output, current-shunt monitors (also called current-sense amplifiers) are commonly used for overcurrent protection, precision-current measurement for system optimization, or in closed-loop feedback circuits.
These devices operate from a single 2.7-V to 26-V power supply, drawing a maximum of 100 A of supply current. All versions are specified from –40 °C to 125 °C, and offered in both SC70-6 and thin UQFN-10 packages.
