Product details

Overview

VNL5160S5TR-E from STMicroelectronics is an automotive-qualified, monolithic low-side driver IC built with VIPower® Technology, designed to switch resistive or inductive loads (e.g., R10W/2×R5W signal lamps) with one side connected to battery voltage. It delivers 3.5 A DC drain current, features 160 mΩ R_DS(on) at 5 V and 25 °C, includes integrated overvoltage clamp (41 V), thermal shutdown with automatic restart, and open-drain status output for diagnostics.

For engineers reviewing the VNL5160S5TR-E datasheet, VNL5160S5TR-E pinout, VNL5160S5TR-E application, or VNL5160S5TR-E equivalent, this device is selected for automotive lighting control where robust fault detection, fast demagnetization of inductive loads, and compliance with 2002/95/EC RoHS are required.

Technical Context

The VNL5160S5TR-E implements a protected PowerMOS stage with active current limitation (I_limH = 3.5–7.5 A), thermal cycling protection (TTSD = 150–200 °C, TR = 135 °C), and open-load detection via STATUS pin. Its CMOS-compatible input includes hysteresis (V_IN(th) = 1–3.5 V, V_IN(hyst) = 0.13 V) and ESD protection (4 kV HBM on INPUT/STATUS/SUPPLY).

It operates from 3.5–5.5 V supply, supports diagnostic feedback through an open-drain STATUS pin (V_STAT ≤ 0.5 V @ I_STAT = 1 mA), and provides fast switching (t_d(ON)/t_d(OFF) = 8.9/13.2 µs) with integrated demagnetization energy handling (E_as = 37 mJ @ L = 8.5 mH).

Key Specifications

Parameter	Value and Actual Design Meaning
Drain current (ID)	3.5 A DC - supports automotive lamp loads up to R10W or dual R5W configurations without external heatsinking under defined thermal conditions.
R_DS(on)	160 mΩ max @ 5 V, 25 °C - ensures <1.8 W conduction loss at 3.5 A, enabling efficient low-side switching in 12 V systems.
V_CLAMP	41 V typ - clamps inductive kickback during turn-off, eliminating need for external flyback diode in many lamp applications.
Thermal shutdown (TTSD)	150 °C min - triggers active power limiting before junction damage; automatic recovery occurs after cooling to ~135 °C.
Status output	Open-drain, logic-low valid during overtemperature, open-load, or undervoltage - enables MCU-level fault classification without additional circuitry.
ESD rating	4000 V HBM on INPUT/STATUS/SUPPLY pins - meets automotive system-level ESD immunity requirements per ISO 10605.
Switching time	t_d(ON) = 8.9 µs, t_d(OFF) = 13.2 µs - enables precise PWM dimming control up to ~20 kHz without excessive switching losses.

Pinout & Package

Package: SO-8 (ECOPACK® compliant, surface-mount, 5.8 × 4.9 mm footprint). Thermal resistance R_thj-amb = 103.1 °C/W on standard FR4 with 0.5 cm² copper pour.

Pin/Terminal	Circuit Role	Design Meaning
INPUT	CMOS-compatible logic input	Hysteresis-enabled control pin (V_IN(th) = 1–3.5 V); internally decoupled from SUPPLY; tolerates ±1 mA clamp current.
DRAIN	PowerMOS drain terminal	High-current output node connected to load; clamped to 41 V during inductive turn-off; handles 3.5 A continuous.
SOURCE	PowerMOS source & ground reference	Common return path for load current and internal control circuitry; must be tied to system ground with low-inductance layout.
SUPPLY	5 V logic supply input	Provides bias for internal logic and protection circuits; requires local 100 nF ceramic decoupling; clamped to 5.5–7 V.
STATUS	Open-drain diagnostic output	Pulled low during overtemperature, open-load, or undervoltage; high-impedance otherwise; requires external pull-up (typically 4.7 kΩ to 5 V).

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 0 (−40 to +150 °C T_j) - validated for under-hood lighting control in passenger vehicles.
Integrated open-load detection	Validated threshold V_OL = 0.6–1.7 V with 45–1100 µs delay - enables reliable bulb-out detection without external comparators.
Active power limitation	Maintains safe dissipation during sustained overload by dynamically reducing I_OUT before thermal shutdown - prevents latch-up and extends fault tolerance.
Low standby current	I_S = 10–25 µA (off-state) - minimizes battery drain in always-on vehicle modules such as daytime running light controllers.
Fast demagnetization support	Enables energy recovery from inductive loads (e.g., solenoids, relays) with E_as = 37 mJ - reduces electromagnetic interference and stress on DRAIN node.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Integrated current sense, 2.6 A max, no STATUS pin, smaller QFN package	Lacks open-load detection and thermal status reporting; suited for space-constrained motor gate drives, not lamp diagnostics	Select only if diagnostic capability is unnecessary and PCB area is critical.
TPS27081A	Higher R_DS(on) (200 mΩ), no overvoltage clamp, no open-load detection, 2.8 A rating	Requires external TVS for inductive kickback; limited to non-automotive industrial loads due to lack of AEC-Q100 qualification	Use only in cost-sensitive, non-automotive applications where clamp and diagnostics are handled externally.

Compared with STSPIN250 and TPS27081A, the VNL5160S5TR-E uniquely combines AEC-Q100 qualification, integrated 41 V clamp, open-load detection, and thermal status reporting in a standard SO-8 package-making it the only drop-in solution for automotive lamp control requiring full diagnostic coverage.

FAQ

What is the maximum continuous drain current for VNL5160S5TR-E?

The VNL5160S5TR-E supports 3.5 A DC drain current under specified thermal conditions (T_j ≤ 150 °C, R_thj-amb = 103.1 °C/W on SO-8 with 0.5 cm² copper). Current is actively limited during overload, and sustained operation above 3.5 A requires derating based on ambient temperature and PCB copper area.

Does VNL5160S5TR-E require an external flyback diode for inductive loads?

No. The device integrates a 41 V overvoltage clamp that safely dissipates demagnetization energy from inductive loads (E_as = 37 mJ), eliminating the need for an external flyback diode in most automotive lamp and solenoid applications.

How does the STATUS pin indicate open-load condition?

During open-load (e.g., broken filament), the STATUS pin pulls low after a delay of 45–1100 µs following INPUT deactivation. This is triggered when V_OL exceeds 1.2 V (typical) at the DRAIN node, enabling unambiguous bulb-out detection without external components.

Can VNL5160S5TR-E be used with 3.3 V microcontrollers?

Yes. Its INPUT pin has CMOS-compatible thresholds (V_IN(th) = 1–3.5 V) and 0.13 V hysteresis, making it directly compatible with 3.3 V logic. No level-shifting is required, though a series resistor (e.g., 1 kΩ) is recommended for MCU I/O protection against drain transients.
