Product details
Overview
UPD166013T1J-E1-AY from Renesas Electronics is a dual-channel N-channel high-side intelligent power switch with integrated charge pump, 90 mΩ typical on-resistance per channel, AEC-Q100 qualified, and embedded diagnostic current sensing for automotive 14 V DC grounded loads such as LED lighting and inductive actuators.
For engineers reviewing the UPD166013T1J-E1-AY datasheet, UPD166013T1J-E1-AY pinout, UPD166013T1J-E1-AY application, or UPD166013T1J-E1-AY equivalent, this device supports fault-aware load control in harsh automotive environments with short-circuit, overtemperature, reverse-battery, and loss-of-ground protection - critical for ECU output stage design and functional safety compliance.
Technical Context
The UPD166013T1J-E1-AY integrates two independent high-side switches sharing a single VCC supply and thermal sensor, each featuring active clamp operation during inductive load turn-off and proportional current sense (KILIS = 1950–7700 A/A) referenced to IS pins. Its charge pump enables full enhancement of N-channel MOSFETs without external bootstrap components.
Protection logic implements three-tiered short-circuit detection: immediate shutdown at >12 A (VCC = 13.5 V), delayed overload detection after 400 µs, and thermal shutdown at 150 °C with 10 °C hysteresis. Fault signaling is delivered via fixed 6.2 V VIS,fault output when abnormal conditions are detected.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | Dual independent high-side outputs for parallel or separate load control |
| On-resistance (Ron) | 90 mΩ typ. per channel at Tch = 25 °C - enables <2.5 A continuous load drive with <230 mW conduction loss |
| Current sense ratio (KILIS) | 2525 A/A typ. at 2.2 A load - delivers ~0.87 mA IS output for precise MCU ADC monitoring |
| Short-circuit detection threshold | 12 A typ. at VCC = 13.5 V - robust against transient surges while ensuring fast fault response |
| Thermal shutdown temperature | 150 °C with 10 °C hysteresis - prevents latch-up and enables auto-restart after cooling |
| Supply voltage range | 5.5 V to 28 V - covers cold-crank (6 V) to load-dump (40 V transient) automotive battery conditions |
| AEC-Q100 qualification | Qualified per Grade 1 (–40 °C to +125 °C ambient) - validated for under-hood automotive applications |
Pinout & Package
Package: 12-pin Power HSSOP (JEITA PRSP0013FA-A), exposed thermal tab, RoHS-compliant pure tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Common return path for logic and protection circuitry; must connect directly to PCB ground plane |
| IN1 / IN2 | Channel enable inputs | CMOS-compatible digital inputs (VIH = 3.0 V min); internal pull-down ensures safe off-state on open input |
| OUT1 / OUT2 | Protected high-side outputs | Switched 14 V DC power outputs; require 50–100 nF local decoupling to suppress switching noise |
| IS1 / IS2 | Proportional current sense outputs | Analog current sources (IIS = IL/KILIS) - connect to GND via 2–5 kΩ resistor for voltage readout |
| SEN | Diagnostic enable | Active-high control for current sense and open-load detection; disables IS output when low |
| VCC | Power supply | Single 5.5–28 V input powering both logic and output stages; requires 100 nF ceramic bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Enables full N-MOSFET enhancement without external bootstrap capacitor or diode - reduces BOM count and layout area |
| Dynamic clamp operation | Activates only during inductive turn-off to limit VOUT negative swing - eliminates need for external flyback diodes |
| Loss-of-ground protection | Maintains defined ON/OFF state even if GND pin disconnects while load remains grounded - improves system fail-safe behavior |
| Reverse-battery tolerance | Withstands –16 V at VCC and limits reverse current to 90 mA - protects against incorrect battery installation |
| Under-voltage lockout (UVLO) | Shuts down outputs below 5.5 V and auto-resumes above threshold - prevents erratic switching during cranking |
Applications
| Automotive LED Headlamp Control | Body Control Module (BCM) Load Switching |

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 |
|---|---|---|---|
| INFINEON BTS724G | Single-channel, 10 mΩ Ron, no integrated charge pump - requires external bootstrap; 40 V abs max VCC | Higher current capability (40 A peak) but lacks dual-channel integration and proportional current sense | Select for higher-power single-load applications where board space allows external bootstrap and discrete sensing |
| ONSEMI NCV8460A | Dual-channel, 120 mΩ Ron, no charge pump, no dynamic clamp - relies on external flyback diode | Lower cost and smaller SOIC-8 package but lacks inductive clamp and AEC-Q100 Grade 1 rating | Select for non-safety-critical interior loads where thermal margin and fault coverage are less stringent |
Compared with UPD166013T1J-E1-AY, BTS724G offers superior current handling but demands more external components and lacks dual-channel consolidation, while NCV8460A trades diagnostic fidelity and ruggedness for compactness and cost - making UPD166013T1J-E1-AY optimal for AEC-Q100-compliant dual-load systems requiring integrated protection and current telemetry.

FAQ
What is the maximum continuous load current supported by UPD166013T1J-E1-AY per channel?
The UPD166013T1J-E1-AY does not specify a fixed maximum continuous current rating; instead, it self-limits based on thermal dissipation. With 90 mΩ typical Ron and 30 °C/W junction-to-ambient thermal resistance, continuous current is constrained to ~2.5 A at 85 °C ambient on a standard 50 mm × 50 mm PCB. Derating is required at higher temperatures or with reduced copper area. The UPD166013T1J-E1-AY datasheet provides detailed thermal curves for precise system-level calculation.
Does UPD166013T1J-E1-AY require an external bootstrap capacitor?
No, the UPD166013T1J-E1-AY integrates a charge pump that generates the gate drive voltage needed for its internal N-channel MOSFETs, eliminating the need for an external bootstrap capacitor or diode. This simplifies PCB layout and improves reliability in space-constrained automotive modules. The UPD166013T1J-E1-AY achieves full enhancement across its entire 5.5–28 V VCC operating range using only the single VCC supply.
How does UPD166013T1J-E1-AY handle inductive load turn-off?
The UPD166013T1J-E1-AY features an internal dynamic clamp circuit that activates automatically during inductive turn-off, limiting VOUT to 24 V (typ.) and dissipating up to 17 mJ per pulse. This eliminates the need for external flyback diodes while protecting downstream components. The UPD166013T1J-E1-AY's clamp operates only when required - during negative VOUT excursions - and remains inactive during normal operation or overvoltage events.
Can UPD166013T1J-E1-AY detect open-load conditions?
Yes, the UPD166013T1J-E1-AY detects open-load conditions in the OFF state by monitoring VOUT; when VOUT exceeds 3.2 V (typ.), it asserts a fault signal on the IS pin. This function requires the SEN pin to be high and a pull-up resistor on the load side. The UPD166013T1J-E1-AY distinguishes open-load from short-to-VCC faults using different VIS,fault timing and voltage thresholds, enabling precise diagnostic classification in ECUs.
What is the purpose of the RGND pin in UPD166013T1J-E1-AY?
The RGND pin in UPD166013T1J-E1-AY is not a dedicated pin - it refers to an internal 140 Ω resistor placed between the GND pin and the internal logic ground, used to detect loss-of-ground conditions. When the GND pin disconnects, this resistor allows the internal circuitry to remain biased, enabling the UPD166013T1J-E1-AY to maintain a known output state rather than floating. This feature enhances fail-safe behavior in automotive wiring harnesses prone to corrosion or vibration-induced disconnection.
