Product details

Overview

VN610SPTR-E from STMicroelectronics is a single-channel automotive-grade high-side driver IC designed for controlling resistive or inductive loads (e.g., solenoids, lamps, motors) with one side grounded. It delivers 45 A DC output current, features 10 mΩ R_DS(on) at 25°C, integrated proportional current sense (K ≈ 4400), and operates across 5.5–36 V V_CC. Used in engine control modules and body electronics for robust load switching under harsh automotive transients.

For engineers reviewing the VN610SPTR-E datasheet, VN610SPTR-E pinout, VN610SPTR-E application, or VN610SPTR-E equivalent, key selection criteria include ISO 7637-2 transient immunity (Pulse 1–5), thermal shutdown behavior (T_SD = 150°C), current sense accuracy (±10% drift over temperature), and PowerSO-10 package thermal resistance (R_thj-case = 0.9°C/W).

Technical Context

The VN610SPTR-E integrates VIPower™ M0-3 technology to combine power DMOS output stage with CMOS logic and analog sensing circuitry. Its active V_CC clamp (41–55 V) and internal current limitation (45–120 A) enable direct compatibility with 12 V/24 V automotive systems subject to load dump and reverse battery conditions.

It implements dual protection coordination: undervoltage lockout (V_USD = 4 V typ.) disables output below safe operating voltage, while overvoltage shutdown (V_OV = 36 V) triggers before clamp activation. Thermal shutdown (150°C) and automatic restart provide fault recovery without external intervention.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	5.5–36 V: Supports full automotive battery range including cold-crank (5.5 V) and load dump (36 V clamped).
R_DS(on)	10 mΩ @ 15 A, 25°C: Enables <1.5 W conduction loss at 45 A, critical for thermally constrained PCB layouts.
I_OUT Max	45 A DC: Rated continuous output current with internal current limiting and thermal foldback.
Current Sense Ratio K	4400 typ. (I_OUT/I_SENSE): Delivers accurate real-time load monitoring with ±10% ratio drift over –40°C to +150°C.
Thermal Shutdown	150°C (T_SD): Triggers automatic output disable and restart cycle to prevent permanent junction damage.
ISO 7637-2 Immunity	Pulse 1–5 compliant: Withstands automotive transients including –100 V (Pulse 1), +100 V (Pulse 2a), and +86.5 V (Pulse 5a) without latch-up or failure.
Standby Current	10 µA @ 13 V: Minimizes battery drain in always-on vehicle subsystems (e.g., alarm, CAN wake-up circuits).

Pinout & Package

Package: PowerSO-10 - thermally enhanced surface-mount package with exposed die pad for low R_thj-case (0.9°C/W), optimized for high-current automotive PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUTPUT)	Power Output	High-side switched output terminal; connects to load anode; rated for 45 A DC and reverse battery protection.
2 (GND)	Power Ground	Reference return path for output current and internal protection circuits; loss-of-ground detection enabled.
3 (INPUT)	Digital Control Input	CMOS-compatible logic input (V_IL = 1.25 V, V_IH = 3.25 V); includes 0.5 V hysteresis for noise immunity.
4 (CURRENT SENSE)	Analog Current Monitor	Current-source output proportional to I_OUT; requires external R_SENSE to generate voltage signal (e.g., 4 V @ 15 A).
5–6 (N.C.)	No Connect	Internally unused pins; must be left floating per datasheet Table 2.
7–9 (OUTPUT)	Power Output (shared)	Three parallel output pins (1,7,8,9) reduce bondwire resistance and improve current sharing; total 4-pin output structure.
10 (V_CC)	Supply Input	Main power rail input; integrates active clamp diode (V_F ≤ 0.6 V) and overvoltage shutdown (36 V).

Key Features

Feature	Design Value
Proportional Current Sense	Integrated analog I_SENSE output with 4400 typ. gain enables closed-loop load monitoring without external shunt or op-amp.
Reverse Battery Protection	Withstands –13.5 V applied to V_CC and –0.3 V to GND; eliminates need for external series diode in battery feed.
Loss-of-Ground Detection	Automatic output disable if GND pin disconnects; prevents uncontrolled load activation during wiring faults.
Active V_CC Clamp	On-chip Zener-like clamp limits V_CC to 41–55 V during transients, reducing or eliminating need for external TVS.
Low Standby Power	10 µA supply current in OFF state extends battery life in always-powered automotive modules (e.g., gateway ECUs).

Applications

Engine Cooling Fan Control

Headlamp Beam Switching

Use Scenario: PWM-controlled 12 V DC brushless fan in engine bay, subject to 150°C ambient and ISO 7637 load dump pulses.

IC Role / Device Role / Timing Role: High-side switch providing ON/OFF and current feedback to MCU for stall detection and thermal derating.

Use Value: Integrated current sense (±10% accuracy) and 45 A rating eliminate external current sensor and enable real-time fan health diagnostics.

Use Scenario: Bi-directional headlamp control (low/high beam) in modern LED headlamps with adaptive driving beam (ADB) logic.

IC Role / Device Role / Timing Role: High-side driver with fast turn-on/turn-off (t_d(on)/t_d(off) ≤ 50 µs) enabling precise PWM dimming and beam pattern modulation.

Use Value: Low R_DS(on) (10 mΩ) minimizes power loss in high-current beam paths; thermal shutdown prevents LED array damage during thermal runaway.

Transmission Solenoid Driver

Body Control Module (BCM) Power Distribution

Use Scenario: 24 V commercial vehicle transmission solenoid actuation requiring precise current regulation and short-circuit tolerance.

IC Role / Device Role / Timing Role: Fault-tolerant high-side driver with programmable current limit (45–120 A) and diagnostic current sense for solenoid coil integrity check.

Use Value: Proportional current sense enables coil resistance measurement at startup; overtemperature restart avoids solenoid burnout during extended engagement.

Use Scenario: Centralized 12 V power distribution in automotive BCM for door locks, window lifts, and mirror controls.

IC Role / Device Role / Timing Role: Protected high-side switch with undervoltage lockout (4 V) and reverse battery immunity ensuring reliable operation during cranking and jump-start events.

Use Value: Loss-of-ground detection prevents unintended actuation if ground cable corrodes; low standby current (<10 µA) meets OEM quiescent current budgets.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS716G	Lower I_OUT (27 A), higher R_DS(on) (18 mΩ), no integrated V_CC clamp	Requires external TVS for ISO 7637 Pulse 5; suited for lower-power solenoids or valves	Select when cost sensitivity outweighs need for 45 A rating and integrated clamp.
NXP MC33883	Higher V_CC max (40 V), but no proportional current sense (only fault flag), larger SOIC-16 package	Lacks analog current feedback; used where only ON/OFF control and fault reporting are required	Select when system-level current sensing is handled externally or not needed.

Compared with VN610SPTR-E, BTS716G offers lower conduction loss at 27 A but lacks automotive transient clamping and proportional sensing; MC33883 provides higher voltage margin but sacrifices real-time load monitoring capability essential for predictive diagnostics.

FAQ

What is the maximum continuous output current rating for VN610SPTR-E?

The VN610SPTR-E is rated for 45 A DC continuous output current under specified thermal conditions (T_c ≤ 25°C, R_thj-case = 0.9°C/W). Actual achievable current depends on PCB copper area and ambient temperature; at T_c = 100°C, derated current is approximately 28 A per ST's thermal curves (Figure 14).

How does the current sense function interface with a microcontroller ADC?

The CURRENT SENSE pin delivers a proportional current (I_SENSE = I_OUT/K, K ≈ 4400). An external resistor (e.g., 3.9 kΩ) converts this to voltage (e.g., 3.9 V @ 15 A). The output is ratiometric and linear across –40°C to +150°C, with 500 µs delay (t_DSENSE), requiring ADC sampling synchronization for accurate capture.

Does VN610SPTR-E require external components for ISO 7637-2 Pulse 5a compliance?

No external TVS is required for ISO 7637-2 Pulse 5a (load dump up to +86.5 V) due to its integrated V_CC clamp (41–55 V) and overvoltage shutdown (36 V). However, a small ceramic capacitor (≥100 nF) between V_CC and GND is mandatory per datasheet Section 4.1 to stabilize clamp response and meet transient immunity test requirements.

Can VN610SPTR-E drive inductive loads without external freewheeling diodes?

Yes - the device integrates an internal freewheeling path via its V_CC-clamp diode (V_F ≤ 0.6 V at 8 A, T_j = 150°C). This allows safe demagnetization of inductive loads (e.g., solenoids, relays) without external diodes, provided energy dissipation stays within E_MAX = 193 mJ (L = 0.05 mH, V_bat = 13.5 V, I_L = 75 A).
