What are the key features of VN340SP-E?
- Quad low-side channel architecture drives 4 independent loads up to 0.7A each from a single SOP-10 package
- Integrated transient, thermal, and under-voltage lockout protections eliminate external protection components in relay and solenoid drive circuits
- Logic-compatible inputs allow direct interface from 3.3V or 5V MCU GPIO pins without external buffers
- Current-sink output topology suitable for driving inductive loads such as relays, solenoids, and small DC motors
What is VN340SP-E used for?
VN340SP-E drives relay coils, solenoid valves, indicator lamps, and small DC motors in industrial automation, home appliance, and automotive body electronics applications. Its 4-channel low-side driver configuration with 0.7A per channel eliminates discrete transistor arrays in PLC output modules and HVAC control boards. The on-chip transient and thermal protection ensures reliable operation across the full automotive temperature range without external protection circuits.

Frequently Asked Questions
How many output channels does VN340SP-E provide, and what is the per-channel current rating?
VN340SP-E provides 4 independent low-side sink channels, each rated at 0.7A maximum continuous output current. This allows a single SOP-10 device to control 4 relay coils, solenoids, or small lamps simultaneously, replacing a 4-transistor discrete driver array in PLC output stages and appliance control boards.
What built-in protections does VN340SP-E include, and how do they help in relay-driving circuits?
VN340SP-E integrates transient voltage protection, thermal shutdown, and under-voltage lockout in each channel. Inductive relay coils generate flyback spikes up to several hundred volts; the built-in transient clamp handles these without external freewheeling diodes. Thermal shutdown at the junction protects the IC when all 4 channels switch high-current loads simultaneously, reducing BOM and improving long-term reliability.
How does VN340SP-E interface with a 3.3V microcontroller driving industrial relay outputs?
VN340SP-E accepts logic-level inputs compatible with 3.3V and 5V MCU GPIO pins, so no level-shifter or buffer is needed between a low-voltage controller and the high-side load. When the MCU drives a logic-high input, the corresponding low-side channel sinks up to 0.7A through the relay coil, enabling direct 3.3V MCU control of 12V or 24V industrial relay loads.
In what scenario would a designer choose VN340SP-E over a discrete MOSFET array for a 4-relay automotive body control module?
VN340SP-E reduces component count from at least 8 discrete parts (4 MOSFETs plus 4 gate resistors) to a single 10-pin IC that includes integrated protection and logic input buffers. In 12V automotive body control modules driving 4 relay coils at 0.7A each, the integrated under-voltage lockout and thermal protection meet AEC-Q100 reliability expectations without additional external protection circuits.
