Q & A
- What is the VND5025AK-E used for? The VND5025AK-E is used for driving resistive or inductive loads with one side connected to ground and is suitable for driving LEDs in automotive applications.
- What is the operating voltage range of the VND5025AK-E? The operating voltage range is from 4.5V to 36V.
- What is the maximum on-state resistance per channel? The maximum on-state resistance per channel is 25 mΩ.
- What protection features does the VND5025AK-E have? It includes undervoltage shut-down, overvoltage clamp, load current limitation, self-limiting of fast thermal transients, protection against loss of ground and loss of VCC, thermal shutdown, reverse battery protection, and electrostatic discharge protection.
- How does the current sense feature work? The device integrates an analog current sense that delivers a current proportional to the load current when CS_DIS is driven low or left open.
