Product details
Overview
VND5E050MCJTR-E from STMicroelectronics is a double-channel high-side driver IC for 12 V automotive grounded loads, featuring integrated analog current sense per channel, 50 mΩ typical on-state resistance, 27 A typical current limitation, and CMOS-compatible 3.0 V logic inputs. It delivers active power limitation for inrush/overload management, thermal shutdown with auto-restart, and reverse-battery protection-used in body control modules to drive solenoids and lighting loads.
For engineers reviewing the VND5E050MCJTR-E datasheet, VND5E050MCJTR-E pinout, VND5E050MCJTR-E application, or VND5E050MCJTR-E equivalent, key selection criteria include channel-wise current sense accuracy (±15% K-ratio drift over temperature), dual-channel thermal independence, PowerSSO-12 package thermal resistance (2.7 °C/W junction-to-case), and diagnostic enable/disable via CS_DIS pin.
Technical Context
This device implements two independent VIPower® M0-5 high-side switches with dedicated analog current sense outputs (CS1/CS2) and a shared CMOS-compatible CS_DIS input. Each channel provides proportional current sensing (K₀ = 1440–3630 A/A), overload detection via active power limitation, and thermal shutdown at 150–200 °C with 7 °C hysteresis.
Protections include undervoltage shutdown (4.5 V nominal), overvoltage clamp (41–52 V), load current limitation (19–38 A), and loss-of-ground/VCC detection. The 3.0 V logic interface supports direct connection to automotive microcontrollers without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max supply voltage | 41 V - withstands automotive load-dump transients without external clamping |
| Operating voltage range | 4.5 V to 28 V - supports cold-crank (4.5 V) and boosted battery (28 V) conditions |
| On-state resistance (per ch.) | 50 mΩ typ. at 25 °C - enables <100 mV output drop at 2 A, minimizing power loss |
| Current limit (typ.) | 27 A - limits fault energy during short-to-ground while sustaining diagnostics |
| Standby supply current | 2 µA - ensures ultra-low quiescent draw in always-on vehicle domains |
| Current sense ratio (K₁) | 1740–2070 A/A at 1 A - enables ±15% full-range analog feedback for ECU current monitoring |
| Thermal shutdown threshold | 150 °C - triggers auto-restart after cooling to ≥135 °C, enabling fault-tolerant operation |
Pinout & Package
Housed in PowerSSO-12 package with exposed thermal pad connected to VCC. Pin 1 is CS_DIS; pins 2–3 are GND; pins 4–5 are IN1/IN2; pins 6–7 are CS1/CS2; pins 8–9 are OUT1/OUT2; pins 10–12 are VCC (including thermal tab).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | CMOS-compatible logic input | 3.0 V–5.0 V compatible; 0.9 V low / 2.1 V high thresholds with 0.25 V hysteresis |
| OUT1, OUT2 | High-side power output | Drives grounded resistive/inductive/capacitive loads; integrates fast demag clamp (VCC−41 V) |
| CS1, CS2 | Analog current sense output | Sinks proportional current (ISENSE = IOUT/K); supports external resistor-based voltage conversion |
| CS_DIS | Active-high sense disable | Pulling high disables both CS1/CS2 outputs, enabling shared sense resistor across multiple devices |
| VCC | Main supply and thermal pad | Connects to battery rail; thermal tab must be soldered to PCB copper for Rthj-case = 2.7 °C/W |
| GND | Signal ground reference | Must be reverse-battery protected externally via diode/resistor network per datasheet Figure 3.1 |
Key Features
| Feature | Design Value |
|---|---|
| Inrush current management | Active power limitation prevents voltage sag during capacitive load turn-on without external circuitry |
| Diagnostic flexibility | CS_DIS pin allows dynamic enable/disable of analog sense channels to reduce BOM count in multi-driver systems |
| EMC robustness | Optimized switching slope (dV/dt) and layout-aware design meet automotive CISPR 25 Class 5 emission limits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VND5E025MJTR-E | 25 mΩ RON, 40 A current limit, PowerSSO-12 | Higher conduction efficiency but reduced thermal margin in compact layouts | Select when lower I²R loss is critical and PCB copper area supports higher power dissipation |
| TPS4H160-Q1 | Single-channel, 160 mΩ RON, SPI-configurable diagnostics, HTSSOP-20 | Configurable protection thresholds and fault reporting via serial interface | Choose when system requires programmable trip points or multi-device daisy-chaining |
Compared with VND5E050MCJTR-E, the VND5E025MJTR-E offers lower conduction loss but less thermal headroom in dense layouts, while the TPS4H160-Q1 trades analog current sense simplicity for digital configurability and single-channel scalability.

FAQ
What is the function of the CS_DIS pin?
The CS_DIS pin is an active-high CMOS-compatible input that disables both analog current sense outputs (CS1 and CS2) when driven above 2.1 V. This allows sharing of a single external sense resistor across multiple VND5E devices in multi-channel systems, reducing component count and PCB footprint while maintaining diagnostic capability on demand.
Can VND5E050MCJTR-E drive inductive loads like fuel injectors?
Yes. The device integrates a demagnetization voltage clamp (VDEMAG = VCC − 41 V) and supports up to 3 mH inductance at 13.5 V supply, enabling safe turn-off of automotive solenoids and injectors. Its 27 A current limit and thermal shutdown with auto-restart protect against sustained short-circuit faults during coil de-energization.
How does the device handle reverse battery conditions?
VND5E050MCJTR-E tolerates −0.3 V on VCC and −200 mA on GND without damage. However, the GND pin requires external reverse-battery protection-either a series resistor (RGND) or Schottky diode (DGND)-as specified in Section 3.1 of the datasheet. This network prevents latch-up and ensures reliable operation during battery polarity reversal events.
Is the PowerSSO-12 package thermally enhanced?
Yes. The PowerSSO-12 package features an exposed VCC thermal pad that achieves 2.7 °C/W junction-to-case thermal resistance when soldered to ≥100 mm² of 2-oz copper. This enables 4.5 W continuous power dissipation per channel at 150 °C junction temperature, making it suitable for high-duty-cycle automotive loads without forced airflow.
