Product details
Overview
L6376D013TR from STMicroelectronics is a quad-channel high-side intelligent power switch in PowerSO-20 package, designed for driving inductive, capacitive, or resistive loads in industrial control systems. It delivers 0.5 A per channel, operates from 9.5 V to 35 V supply, features non-dissipative overcurrent protection, thermal shutdown, and open-drain diagnostic output reporting UV/OVT/OVC faults.
For engineers reviewing the L6376D013TR datasheet, L6376D013TR pinout, L6376D013TR application, or L6376D013TR equivalent, this device is selected for robust load switching where programmable short-circuit timing, fault diagnostics, and immunity to IEC 61000-4-4 burst transients are required in PLC I/O modules, motor starters, and valve drivers.
Technical Context
The L6376D013TR integrates four independent high-side switches with internal current limiting (typ. 800 mA), each controlled by TTL/CMOS-compatible inputs with 100–400 mV hysteresis. Its multipower BCD process enables on-resistance low enough to sustain 500 mA with ≤640 mV drop at 125 °C.
Diagnostic logic uses an open-drain output (pin 19) that asserts low during undervoltage (VS < 9 V), overtemperature (TJ > 150 °C), or overcurrent events. Programmable ON/OFF delay timing (1.28 µs/pF) allows configurable short-circuit recovery via external capacitors on pins 16 and 17.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output channels | 4 independent high-side switches with individual current limit and diagnostic reporting |
| Supply voltage range | 9.5 V to 35 V DC - supports wide industrial rail voltages; UVLO activates below 8.5 V |
| Continuous output current | 0.5 A per channel - rated for sustained load drive without thermal derating at 85 °C ambient |
| Output voltage drop | ≤640 mV at 500 mA and 125 °C - ensures minimal power loss and heat generation under worst-case junction temp |
| Short-circuit response | Non-dissipative protection with programmable tON/tOFF (64 µs to 15 ms) - avoids thermal runaway during sustained faults |
| Diagnostic output | Open-drain, active-low signal indicating UV, OVT, or OVC - enables wired-OR fault bus for multi-device monitoring |
| ESD immunity | ±2 kV HBM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
Package: PowerSO-20 - thermally enhanced surface-mount package with exposed die pad (pins 1, 10, 11, 20 as GND/power dissipation paths); RthJC = 1.5 °C/W enables high-power operation with PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 2, 3, 8, 9 (O1–O4) | High-side output terminals | Each drives load between VS and output; integrated clamp diodes enable inductive demagnetization |
| 12–15 (I1–I4) | Digital input control lines | TTL/CMOS-compatible; 1.35 V threshold with 200 mV hysteresis prevents noise-induced toggling |
| 6 (VS) | Main supply input | Monitored for UVLO; diagnostic available down to 5 V, but functional operation requires ≥9.5 V |
| 7 (VCP) | Charge pump driver supply | Internally boosted ~10 V above VS to ensure full enhancement of high-side DMOS; requires 22 nF filter cap |
| 16 (ON DELAY) | Programmable short-circuit ON time | External capacitor sets tON = 1.28 µs/pF (50 pF–15 nF); disables non-dissipative protection if grounded |
| 17 (OFF DELAY) | Programmable short-circuit OFF time | External capacitor sets tOFF = 1.28 µs/pF; ties to ground for tOFF = 64 × tON |
| 18 (R) | Asynchronous reset | Active-low; forces all outputs OFF regardless of input states - used for CPU-initiated safe shutdown |
| 19 (DIAG) | Fault reporting output | Open-drain; pulled low during UV, OVT, or OVC - remains inactive during tON even under short circuit |
Key Features
| Feature | Design Value |
|---|---|
| Non-dissipative overcurrent protection | Prevents thermal runaway by cycling output into linear mode (800 mA) then OFF state - avoids global thermal shutdown |
| Programmable fault timing | Independent ON/OFF delay via external capacitors enables tuning for surge-tolerant loads (e.g., solenoids, lamps) |
| Integrated charge pump | Generates ~11 V bootstrap voltage (pin 4 VP) at 200 kHz to fully enhance high-side DMOS without external boost circuitry |
| IEC 61000-4-4 immunity | Built-in transient suppression eliminates need for external TVS on VS or outputs in standard industrial environments |
| Open-ground protection | Detects loss of GND connection across pins 1/10/11/20 and disables outputs - prevents latch-up or erratic behavior |
Applications
| PLC Digital Output Module | Industrial Solenoid Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side intelligent power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VNS3NV04PTR-E | Single-channel 4 A high-side switch; no integrated diagnostic output or programmable delay | Lacks multi-channel integration and fault reporting - requires external logic for quad functionality | Select when higher current per channel (4 A) is needed and diagnostics are handled externally |
| IPS1032HTR | Quad-channel 3.2 A switch with SPI interface and enhanced diagnostics (channel-specific flags) | Requires microcontroller SPI interface; supports daisy-chained configuration and advanced fault logging | Select for next-gen designs needing digital configurability and granular fault data beyond open-drain DIAG |
Compared with VNS3NV04PTR-E and IPS1032HTR, the L6376D013TR offers optimal balance of analog simplicity, built-in diagnostics, and cost-effective quad integration for legacy and cost-sensitive industrial I/O systems without MCU dependency.

FAQ
What is the minimum supply voltage required for L6376D013TR to enable output switching?
The device enters functional operation only when VS reaches 9.5 V; below 8.5 V, undervoltage lockout forces all outputs OFF. Diagnostic reporting remains active down to 5 V, but no channel switching occurs until the upper UV threshold (9–9.5 V) is crossed with sufficient hysteresis margin.
Can the L6376D013TR drive inductive loads without external flyback diodes?
Yes - it integrates four clamping diodes capable of demagnetizing inductive loads. However, peak energy per channel must stay below 200 mJ at TJ = 125 °C; larger inductors or simultaneous multi-channel demag require external diodes tied to VS or GND per Figure 7 and Figure 8.
How does the non-dissipative overcurrent protection differ from traditional thermal shutdown?
Instead of waiting for junction temperature to trigger global shutdown, the L6376 cycles each overloaded channel between linear-mode current limit (800 mA) and OFF state using programmable tON/tOFF. This keeps average power dissipation low, preventing thermal propagation and allowing unaffected channels to remain operational.
Is the DIAG output compatible with 3.3 V logic systems?
Yes - DIAG is an open-drain output with 1.5 V max voltage drop at 5 mA sink current. When pulled up to 3.3 V via external resistor, it cleanly interfaces with 3.3 V microcontrollers; its active-low assertion directly signals UV/OVT/OVC without level-shifting.
