Product details
Overview
VND5E050MKTR-E from STMicroelectronics is a double-channel high-side driver in PowerSSO-24 package, designed for 12 V automotive grounded loads. It delivers 50 mΩ on-state resistance per channel, 27 A typical current limitation, and proportional analog current sense (K₀ = 2250) with CMOS-compatible 3.0 V inputs. Used in LED lighting, solenoid control, and body electronics where diagnostics and reverse-battery protection are required.
For engineers reviewing the VND5E050MKTR-E datasheet, VND5E050MKTR-E pinout, VND5E050MKTR-E application, or VND5E050MKTR-E equivalent, key selection criteria include its dual-channel thermal shutdown with auto-restart, ±15% current sense ratio drift over temperature, 4.5–28 V operating range, and integrated overvoltage clamp up to 52 V - all validated for ISO 16750-2 load dump and AEC-Q100 automotive compliance.
Technical Context
This device implements active power limitation for inrush and overload management via real-time output voltage drop control (VON ≤ 25 mV at 0.1 A), coupled with thermal shutdown at 150 °C and auto-restart after cooling to ≥135 °C. Each channel features independent analog current sense (CS1/CS2) with disable control (CS_DIS) and hysteresis-enabled CMOS inputs (VIH = 2.1 V, VIL = 0.9 V).
Protection architecture includes undervoltage shutdown (VUSD = 4.5 V), reverse-battery tolerance via external GND network, and overvoltage clamping (Vclamp = 46 V typ). The VIPower™ M0-5 process enables self-limiting of fast thermal transients and loss-of-ground/loss-of-VCC detection without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max supply voltage | 41 V - withstands ISO 16750-2 load dump transients without external clamp |
| Operating voltage range | 4.5 V to 28 V - supports cold-crank (4.5 V) and boosted battery (28 V) conditions |
| RON (per channel) | 50 mΩ @ 25 °C - enables <1 W conduction loss at 10 A, reducing heatsink requirements |
| Current limit (typ) | 27 A - sustains short-circuit events while limiting peak junction temperature rise |
| Standby current | 2 µA - minimizes battery drain in always-on vehicle modules (e.g., door modules) |
| Current sense ratio (K₀) | 2250 - delivers 444 nA sense current per 1 A load, enabling high-resolution ADC interfacing |
| Thermal shutdown | 150 °C with 15 °C hysteresis - prevents permanent damage during sustained overload |
Pinout & Package
Package: PowerSSO-24 (exposed thermal pad tied to VCC), RoHS-compliant, ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary power rail; connects to exposed thermal pad for enhanced heat dissipation |
| GND | Ground reference | Must be protected against reverse battery via external diode/resistor network per Figure 29 |
| OUT1, OUT2 | High-side power outputs | Drive grounded resistive/inductive/capacitive loads; each internally limited to 27 A |
| IN1, IN2 | CMOS-compatible control inputs | Hysteresis (0.25 V) prevents noise-induced switching; compatible with 3.0 V/5.0 V MCUs |
| CS1, CS2 | Analog current sense outputs | Deliver proportional ISENSE = IOUT/K₀; enable real-time load monitoring and fault detection |
| CS_DIS | Current sense disable control | Active-high logic disables both CS pins, allowing shared external sense resistor across multiple devices |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel diagnostic current sense | Independent CS1/CS2 pins with ±15% full-temperature-range accuracy (K₀ drift) for precise load monitoring |
| Active power limitation | Real-time VON regulation limits output voltage drop to ≤25 mV at 0.1 A, preventing thermal runaway during inrush |
| Reverse battery protection support | Integrated design allows external GND-line protection (diode or resistor) per Figure 29 - no internal diode required |
| Automotive-grade EMI/EMS | Optimized layout and internal filtering meet stringent OEM EMC requirements (ISO 11452, ISO 7637) |
| Thermal auto-recovery | Shuts down at 150 °C and restarts only after junction cools to ≥135 °C - avoids system lockup during transient overloads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Single-channel, 160 mΩ RON, no analog current sense - uses digital SPI diagnostics | Suitable for lower-current (<2 A), digitally managed systems requiring functional safety (ASIL-B) | Select when system-level diagnostics require ASIL-B compliance and current sensing is handled externally |
| VND7050AJTR-E | Same PowerSSO-24 package, 50 mΩ RON, but single-channel and lacks CS_DIS pin | Used where space-constrained designs need identical footprint but only one channel is required | Select when dual-channel functionality is unnecessary and cost reduction per channel is prioritized |
Compared with TPS4H160-Q1 and VND7050AJTR-E, the VND5E050MKTR-E uniquely combines dual-channel operation, analog current sense with disable capability, and automotive-qualified thermal auto-restart - making it optimal for cost-sensitive, high-diagnostic-fidelity body electronics where pin count and analog integration matter.

FAQ
What is the maximum continuous output current per channel?
The VND5E050MKTR-E does not specify a fixed maximum continuous current due to thermal dependency. Its 27 A typical current limit applies during short-circuit conditions. Continuous current capability depends on PCB copper area, ambient temperature, and switching duty cycle - for example, 8 A is sustainable with ≥200 cm² of 2 oz copper in free-air conditions per Figure 37.
How does the CS_DIS pin function in multi-device configurations?
When CS_DIS is pulled high, both CS1 and CS2 outputs are disabled, allowing their sense nodes to be tied together and connected to a single external sense resistor and ADC input. This reduces component count and PCB area in systems with multiple VND5E050MKTR-E devices sharing diagnostic resources.
Is reverse battery protection implemented internally?
No. Reverse battery protection requires an external network on the GND line - either a series resistor (RGND) or Schottky diode (DGND) - as detailed in Section 3.1 of the datasheet. The device itself tolerates reverse ground current up to 200 mA but relies on external components for full protection.
Can this device drive inductive loads without external flyback diodes?
Yes - the integrated overvoltage clamp (Vclamp = 46 V typ.) safely absorbs demagnetization energy from inductive loads like solenoids and relays. However, for high-energy inductors (L > 10 mH), external clamping may still be recommended to limit peak VCC stress during rapid turn-off.
