Working Principles

The BTS70402EPAXUMA1 power switch operates by controlling the flow of current through the load connected to its output channels. The input control signals (IN1 and IN2) determine whether the corresponding channel is turned on or off. When a channel is turned on, the power switch allows current to flow from the supply voltage (VS) to the load. The integrated protection features monitor various parameters such as temperature, current, and voltage to ensure safe operation and protect the system from faults.

Detailed Application Field Plans

The BTS70402EPAXUMA1 power switch is primarily designed for use in automotive applications. It can be employed in various systems that require control and protection of high-current loads, such as:

• Automotive lighting systems
• Electric power steering
• Heating, ventilation, and air conditioning (HVAC) systems
• Engine control units (ECUs)
• Battery management systems (BMS)

Detailed and Complete Alternative Models

• BTS7008-1EPA: Similar power switch with lower RDS(ON) and higher current limit
• BTS716G: Power switch with enhanced diagnostic features and lower voltage range
