1NV04D Dual N-Channel Low-Side Driver IC for Automotive HVAC Blower / Fan Control Modules
The 1NV04D is a dual N-channel low-side driver integrated circuit, designed to provide robust and protected power switching for demanding automotive applications.
This component belongs to the OMNIFET II fully autoprotected Power MOSFET family, incorporating advanced VIPower M0-3 technology for reliable operation in harsh environments .
The device integrates two independent power MOSFETs in a compact SO-8 package, making it an efficient solution for driving resistive and inductive loads such as blower motors, fans, relays, and solenoids .
As a common component in automotive body control and HVAC modules, this driver is known to be a frequent failure point in blower motor and fan control circuits.
Typical symptoms of a failing 1NV04D include intermittent fan operation, complete loss of blower function, or erratic behavior of controlled loads.
The chip features comprehensive built-in protection mechanisms including linear current limitation, overtemperature shutdown, overvoltage clamp, and short-circuit protection .
With a maximum load voltage of 36V and continuous output current capability of 1.7A per channel, this driver is compatible with 12V vehicle electrical systems .
Each channel offers a typical on-resistance of 250 mΩ, ensuring efficient power delivery and minimal heat generation during normal operation .
The device also provides diagnostic feedback through the input pin, allowing the control unit to detect fault conditions such as over-temperature events .
Operating across a wide temperature range of -40°C to 150°C, this driver is built to withstand the demanding thermal conditions inside vehicle cabins and engine compartments .
It features a simple on/off interface and requires no external Vcc supply, simplifying the design of control circuits .
This product is a high-quality replacement component, ideal for automotive electronics repair professionals and technicians specializing in HVAC system and blower motor module restorations.
