Product details

Overview

VN808CM-32-E from STMicroelectronics is an octal high-side power switch IC designed for industrial load driving with ground-referenced loads. It features 160 mΩ R_DS(on) per channel, 1 A continuous output current, and 45 V supply voltage capability. Integrated junction and case thermal shutdown, current limitation, undervoltage lockout, and loss-of-ground detection enable robust operation in IEC 61131-compliant PLC output modules.

For engineers reviewing the VN808CM-32-E datasheet, VN808CM-32-E pinout, VN808CM-32-E application, or VN808CM-32-E equivalent, key selection criteria include per-channel thermal independence, CMOS-compatible 3.3 V logic input drive, STATUS fault reporting, and PowerSO-36 package thermal performance (R_th(JC) = 1.3 °C/W).

Technical Context

The VN808CM-32-E implements eight independent VIPower M0-3 high-side switches with active current limiting and dual-stage thermal protection-junction shutdown at 150–200 °C and case shutdown at 125–135 °C. Each channel operates with 160 mΩ on-resistance at 25 °C and supports up to 1 A DC output under 45 V V_CC.

It uses a common open-source STATUS pin to indicate overtemperature faults across any channel, with 2–4 mA high-level drive capability. Input logic thresholds are defined at 1.25 V (low) and 2.25 V (high), with 0.25 V hysteresis, enabling direct interface with 3.3 V microcontrollers without level shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	10.5–32 V DC; ensures compatibility with 12/24 V industrial supplies and avoids false turn-on below 10.5 V due to UVLO
R_DS(on) (per channel)	160 mΩ @ 25 °C; enables <160 mW conduction loss at 1 A, critical for thermally constrained PCB layouts
I_OUT (continuous)	1 A per channel; rated for sustained industrial solenoid, relay, and indicator loads
t_ON/t_OFF	50–100 µs / 75–150 µs; supports fast PWM control and transient load switching in motion control
R_th(JC)	1.3 °C/W; allows precise junction temperature estimation from case measurement in PowerSO-36 package
STATUS Output	Active-high open-source; sinks >2 mA during fault, compatible with standard optocoupler or MCU GPIO inputs
I_IN (max)	±10 mA; permits direct connection to FPGA or MCU GPIO without external series resistors

Pinout & Package

Delivered in PowerSO-36 package with exposed V_CC-connected tab for low-thermal-resistance mounting. The 36-pin layout includes duplicated OUT pins (e.g., OUT1 appears on pins 35 and 36) to reduce trace resistance and improve current sharing.

Pin/Terminal	Circuit Role	Design Meaning
1, 36 (TAB)	V_CC supply input	Primary power rail connection; exposed tab provides thermal path to heatsink or copper pour
6–13	IN1–IN8	CMOS-compatible digital inputs; accept 3.3 V logic directly with 1.25 V/2.25 V thresholds
19	GND	Power ground reference; disconnecting this pin forces automatic channel shutdown
20	STATUS	Common fault indicator; pulled high during junction or case overtemperature events
21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35	OUT1–OUT8 (duplicated)	Eight high-side outputs; each pair (e.g., pins 34+35 for OUT1) must be shorted on PCB for full current rating

Key Features

Feature	Design Value
Dual thermal protection	Junction shutdown (150–200 °C) and case shutdown (125–135 °C) operate independently-non-faulted channels remain active during localized overload
Loss-of-ground detection	Automatic channel disable if GND pin disconnects; prevents uncontrolled load activation in wiring fault scenarios
Short-circuit current limit	0.7–1.7 A per channel; clamps output current during hard shorts while maintaining safe junction temperature
Low standby current	150 µA @ 24 V; reduces system power consumption in idle states of programmable logic controllers
IEC 61000-4-4 compliance	Withstands 4 kV EFT pulses; validated for use in noisy industrial environments without external suppression

Applications

Industrial Motor Starter Control

Use Scenario: Driving 24 V DC solenoids and indicator lamps in modular I/O racks conforming to IEC 61131.

IC Role / Device Role / Timing Role: High-side switch providing galvanically isolated load control with diagnostic feedback via STATUS pin.

Use Value: Enables single-chip replacement of eight discrete MOSFETs + drivers, reducing BOM count and improving thermal reliability.

Use Scenario: Controlling contactor coils in motor starter panels where short-circuit immunity and thermal margin are critical.

IC Role / Device Role / Timing Role: Fault-tolerant power switch with automatic restart after overload clearance and status reporting for HMI integration.

Use Value: Eliminates need for external current-sense amplifiers and thermal sensors-reducing design complexity and board area.

Automated Test Equipment (ATE)

Building Automation System (BAS)

Use Scenario: Sequencing multiple DUT power rails in semiconductor test handlers requiring precise timing and fault logging.

IC Role / Device Role / Timing Role: Precision-controlled high-side driver with sub-100 µs switching and synchronized STATUS assertion for event-triggered diagnostics.

Use Value: Supports deterministic test sequences with real-time fault capture-no software polling required for thermal or short-circuit events.

Use Scenario: Managing HVAC actuators, damper controls, and lighting relays in distributed BAS nodes.

IC Role / Device Role / Timing Role: Robust load interface with built-in reverse polarity protection support and low quiescent current for battery-backed nodes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VN808CM-E	0.7 A continuous output current per channel vs. 1 A; identical R_DS(on), thermal thresholds, and pinout	Lower current rating limits use in higher-power solenoids or parallel-coil configurations	Select when load currents stay ≤700 mA and thermal margin is less constrained
TPS27082L	Single-channel, 2.8 A rated, 40 V max, no case thermal protection, different package (HTSSOP-16)	Lacks multi-channel integration and dual thermal shutdown; requires 8x devices for same functionality	Choose only for space-constrained single-load designs where discrete channel control and higher peak current are prioritized

Compared with VN808CM-E, the -32-E variant delivers 43% higher continuous current per channel while retaining identical protection architecture and footprint-making it optimal for upgraded industrial I/O modules. Against TPS27082L, it offers integrated octal functionality and superior thermal fault isolation but requires larger PCB area.

FAQ

What is the maximum continuous current per channel for VN808CM-32-E?

The VN808CM-32-E supports 1 A continuous DC output current per channel at T_CASE = 25 °C, derating to lower values as case temperature rises. This rating assumes proper PCB copper area (≥0.5 cm² connected to TAB pins) and accounts for internal current limitation and thermal shutdown behavior.

How does the STATUS pin behave during thermal faults?

The STATUS pin is an active-high open-source output that pulls high (>2 mA sink capability) whenever any channel triggers junction overtemperature (T_J > 150–200 °C) or case overtemperature (T_C > 125–135 °C). It remains asserted until both junction and case temperatures fall below their respective reset thresholds (T_JR and T_CR).

Can VN808CM-32-E drive inductive loads like solenoids safely?

Yes-the device includes active current limitation, dV/dt control (0.7–1.5 V/µs), and clamp voltage (V_DEMAG = V_CC−52 V typical) to suppress inductive kickback. For heavy inductive loads, external flyback diodes are still recommended to ensure full energy dissipation and avoid repeated current-limit cycling.

Is the PowerSO-36 package RoHS and REACH compliant?

Yes-VN808CM-32-E is offered in ECOPACK2-compliant PowerSO-36 packaging, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full environmental compliance documentation, including material declarations and lead-free status, is available through STMicroelectronics' official product page and distributor portals.
