Product details

Overview

VN610SP-E from STMicroelectronics is a single-channel automotive-grade high-side driver IC designed for switching resistive or inductive loads connected to ground in 12 V/24 V vehicle systems. It delivers 45 A continuous output current with 10 mΩ R_DS(on), integrates proportional analog current sense (K ≈ 4400), and features undervoltage/overvoltage shutdown, thermal shutdown, reverse-battery protection, and loss-of-ground detection - used in engine control modules, body electronics, and lighting drivers.

For engineers reviewing the VN610SP-E datasheet, VN610SP-E pinout, VN610SP-E application, or VN610SP-E equivalent, key selection criteria include its AEC-Q100 qualification, PowerSO-10 package thermal performance (R_thj-case = 0.9 °C/W), ISO 7637-2 transient immunity, and integrated diagnostic current sense output with ±6% ratio drift over temperature.

Technical Context

The VN610SP-E employs ST's VIPower™ M0-3 BCD technology to integrate power MOSFET, protection logic, and analog current-sense circuitry on a single die. Its active V_CC clamp (41–55 V) and load-dump robustness meet ISO 7637-2 Pulse 1, 2a, 3a/b, and 5a requirements. The device implements dual-stage overcurrent protection: fast current limiting (45–120 A) followed by thermal shutdown at 150–200 °C with 7–15 °C hysteresis.

Control logic accepts CMOS-compatible inputs (V_IL ≤ 1.25 V, V_IH ≥ 3.25 V) and provides status feedback via current-sense pin (I_SENSE = I_OUT/K, K = 4400 typ.) and fault-indicating voltage clamping (V_SENSEH = 5.5 V during overtemperature). Input hysteresis (0.5 V) ensures noise immunity in harsh automotive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	10 mΩ @ I_OUT = 15 A, T_j = 25 °C - enables low conduction loss and <1 W dissipation at 45 A under typical conditions

5 (NC)	No connect	Not internally bonded; must be left floating or tied to ground per layout guidelines
6 (NC)	No connect	Not internally bonded; must be left floating or tied to ground per layout guidelines
7 (V_CC)	Supply input	12/24 V system supply; includes active clamp (41–55 V) and overvoltage shutdown at 36 V
8–10 (OUTPUT)	Power output terminals (shared)	Three parallel output pins (pins 1, 8, 9, 10) reduce bond-wire inductance and improve current sharing

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 0 (−40 °C to +150 °C ambient) - certified for under-hood applications
Reverse-battery protection	Withstands −0.3 V V_CC and −200 mA I_GND - eliminates need for external series diode in battery feed
Proportional current sense	Factory-trimmed K = 4400 ±10% with <±6% drift over −40 °C to +150 °C - enables accurate closed-loop current control
Loss-of-ground detection	Automatic shutdown if GND pin disconnects - prevents uncontrolled load activation and system hazard
Low standby consumption	I_CC = 10 µA max @ V_CC = 13 V - meets automotive quiescent current requirements for always-on modules

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	40 A rating, 12 mΩ R_DS(on), same PowerSO-10 package, but lacks analog current sense - uses digital enable/fault pins only	Suitable for simpler on/off control where analog diagnostics are not required	Select when cost-sensitive designs prioritize basic switching over precision current monitoring
NXP MC33883	35 A rating, 15 mΩ R_DS(on), SOIC-16 package, includes SPI interface and enhanced diagnostics - no integrated V_CC clamp	Better suited for distributed control architectures requiring daisy-chain communication	Select when system-level diagnostics and programmable protection thresholds are needed over passive analog sensing

Compared with VN610SP-E, BTS716G offers lower cost and identical footprint but omits analog current sense; MC33883 adds digital configurability and fault logging at the expense of higher complexity and absence of built-in V_CC clamping - making VN610SP-E optimal for analog-diagnostic–driven, transient-robust automotive power stages.

FAQ

What is the maximum continuous output current rating for VN610SP-E?

The VN610SP-E is rated for 45 A continuous output current under specified thermal conditions (T_c ≤ 25 °C, R_thj-case = 0.9 °C/W). This rating assumes proper PCB copper area (≥6 cm²) and airflow; derating applies above 25 °C case temperature per Figure 14 in the datasheet, where I_LIM decreases to ~75 A at 125 °C case.

Does VN610SP-E require an external current-sense resistor?

No - the VN610SP-E integrates a proportional current-sense function delivering I_SENSE = I_OUT/K (K ≈ 4400) directly at the CURRENT SENSE pin. An external resistor (R_SENSE) is only needed to convert I_SENSE to a measurable voltage (e.g., 10 kΩ yields 0–4.5 V for 0–45 A), as shown in Figure 19 of the datasheet.

How does the VN610SP-E respond to loss of ground connection?

Upon disconnection of the GND pin, the VN610SP-E detects loss of ground reference and automatically disables the output within microseconds. This behavior is implemented in hardware and requires no external circuitry - confirmed in Section 3.1 and Table 11 (Truth Table) of the datasheet, where "Loss of Ground" forces OUTPUT = L and I_SENSE = 0.

Is VN610SP-E compatible with 24 V commercial vehicle systems?

Yes - the VN610SP-E supports V_CC up to 36 V DC and withstands ISO 7637-2 Pulse 5a (up to +86.5 V for 400 ms), making it fully compatible with 24 V truck/bus electrical systems. Its overvoltage shutdown activates at 36 V, and internal clamp operates up to 55 V, providing margin against load-dump transients common in heavy-duty vehicles.
