VNL5090S5TR-E SOIC-8 OMNIFET III Fully Protected Low-Side Driver 13A 90mΩ IC Power Switch Chip
VNL5090S5TR-E Product Overview
The VNL5090S5TR-E is manufactured using ST's proprietary VIPower® technology, integrating a power MOSFET with complete protection circuitry on a single chip. The VNL5090S5TR-E's on-resistance is only 90mΩ typical, with a maximum continuous drain current of 13A, efficiently driving resistive or inductive loads such as automotive signal lamps, relays, and solenoids. Built-in protections include overvoltage clamp (41V), thermal shutdown, output current limitation, and power limitation, which limits dissipated power to a safe level during prolonged overload. Thermal shutdown features automatic restart, allowing the VNL5090S5TR-E to recover to normal operation once the fault condition disappears.
A standout advantage of the VNL5090S5TR-E is its integrated open-drain status output pin, enabling open-load detection to help the system diagnose load connection status. The VNL5090S5TR-E's input control logic is compatible with 3.5V~5.5V supply, allowing direct interfacing with automotive-grade MCU I/O pins without level shifting.

FAQ
Q: What automotive loads is the VNL5090S5TR-E suitable for?
A: The VNL5090S5TR-E is specifically designed for driving 2 × R10W or 4 × R5W automotive signal lamps. It can also drive automotive relays, solenoids, and other resistive or inductive loads. Its 13A maximum drain current and 41V overvoltage clamp capability enable it to handle load dump and voltage transients in automotive electrical systems.
Q: How does the open-load detection function work?
A: The VNL5090S5TR-E integrates an open-drain status output pin. When an open-load condition is detected, the status pin outputs a fault signal to the MCU, helping the system diagnose load connection status. This feature is particularly important for automotive signal lamp systems, providing timely notification of lamp failures.
Q: What protection features are integrated?
A: The VNL5090S5TR-E integrates comprehensive protection including overvoltage clamp (41V), thermal shutdown, output current limitation, and power limitation. Thermal shutdown features automatic restart, recovering normal operation once the fault condition disappears. Fast demagnetization of inductive loads is achieved at turn-off.
Q: What is the difference between VNL5090S5TR-E and VNL5090N3TR-E?
A: Both the VNL5090S5TR-E and VNL5090N3TR-E share essentially identical electrical specifications (13A / 90mΩ / 41V clamp / AEC-Q100). The primary difference is package: VNL5090S5TR-E uses SOIC-8 for a smaller footprint in compact designs; VNL5090N3TR-E uses SOT-223 for better thermal performance in higher-power applications.
