Product details

Overview

UPD166007T1F-E1-AY from Renesas Electronics is a single N-channel high-side intelligent power switch with integrated charge pump, 14 mΩ on-state resistance at 150°C, proportional load current sensing (K_ILIS = 8300–11000), and embedded short-circuit and over-temperature protection. It drives grounded DC loads up to 30 A in automotive lighting and body control modules.

For engineers reviewing the UPD166007T1F-E1-AY datasheet, UPD166007T1F-E1-AY pinout, UPD166007T1F-E1-AY application, or UPD166007T1F-E1-AY equivalent, key selection criteria include its 5-pin TO-252 (MP-3ZK) package, diagnostic IS output with fault signaling, thermal shutdown at 150°C with 10°C hysteresis, and compatibility with 8–18 V supply rails in 14 V automotive systems.

Technical Context

The UPD166007T1F-E1-AY integrates a high-side MOSFET with charge-pump gate driver enabling full enhancement from 8 V V_CC, eliminating need for external bootstrap circuitry. Its control logic monitors V_OUT voltage drop and I_L via proportional sense current (I_IS) to detect overload and short-circuit conditions within microseconds.

Protection is implemented through dual-trigger short-circuit detection-either exceeding programmable I_L(SC) thresholds (e.g., 50 A at V_CC−V_IN = 12 V, V_ON = 3 V) or detecting V_ON > 0.65–1.45 V after 0.8–3.5 ms turn-on delay-and autonomous thermal shutdown at 150°C with auto-restart on cooling.

Key Specifications

Parameter	Value and Actual Design Meaning
On-state resistance	14–18 mΩ at 7.5 A, 150°C - enables low conduction loss in high-current automotive switching
Load current rating	30 A DC continuous - supports 55 W incandescent lamps and solenoid/relay replacement
Supply voltage range	8–18 V - compatible with nominal 14 V automotive battery systems including load dump transients up to 36 V
Current sense ratio	K_ILIS = 8300–11000 - provides accurate proportional feedback for microcontroller ADC monitoring of load current
Short-circuit detection	Programmable threshold from 5–160 A depending on V_CC−V_IN and V_ON - ensures robust fault response across operating conditions
Thermal shutdown	150°C trip, 140°C restart - prevents latch-up during sustained overload while enabling automatic recovery
Fault signal delay	2–6 μs after short-circuit detection - enables fast system-level fault handling without software latency

Pinout & Package

UPD166007T1F-E1-AY uses a JEDEC-standard 5-pin TO-252 (MP-3ZK) surface-mount package with exposed tab for thermal dissipation (R_th(ch-a) = 45–55°C/W on 50 mm × 50 mm FR4 PCB). Pin 1 and Pin 5 are both OUT terminals and must be externally shorted; Pin 3 and the metal tab are internally connected as V_CC.

Pin/Terminal	Circuit Role	Design Meaning
1, 5 (OUT)	High-side power output	Parallel connection required to handle 30 A load current and reduce trace inductance
2 (IN)	Logic-level enable input	Active-low: sink ≥0.7 mA to turn on; open or high-impedance to turn off
3 & Tab (V_CC)	Main power supply	Tab is electrically tied to Pin 3 - must be soldered to large copper area for thermal management
4 (IS)	Diagnostic current sense output	Provides I_IS = I_L/K_ILIS; outputs 3.5–12 mA fault current when protected

Key Features

Feature	Design Value
Built-in charge pump	Enables full MOSFET enhancement from 8 V V_CC, eliminating external gate-drive components
Proportional current sensing	K_ILIS tolerance ±12% over −40 to +150°C - enables precise load monitoring without shunt resistor
Dynamic clamp circuit	Activates only during inductive load switch-off to suppress V_OUT undershoot below GND
Reverse battery protection	V_DS(rev) = 0.6–0.84 V at −40 to +150°C - limits power dissipation during polarity reversal
Pb-free plating	Sn finish compliant with EU RoHS Directive - suitable for lead-free reflow assembly

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
STSPIN840	Lower current rating (10 A), integrated current regulation, SPI interface - no analog IS output	Targeted at stepper motor control, not discrete load switching	Choose STSPIN840 only if closed-loop current regulation and digital command interface are required
TPS4H160-Q1	Higher R_DS(on) (20 mΩ), wider V_CC range (3.5–36 V), integrated watchdog timer - no dynamic clamp	Designed for ASIL-B functional safety compliance with diagnostic coverage reporting	Choose TPS4H160-Q1 when ISO 26262-compliant diagnostics and extended supply range outweigh need for dynamic clamp

Compared with UPD166007T1F-E1-AY, STSPIN840 offers digital control but lacks automotive-grade transient robustness and analog diagnostic capability, while TPS4H160-Q1 adds functional safety features at the cost of higher conduction loss and missing dynamic inductive-clamp protection.

FAQ

What is the maximum continuous load current supported by UPD166007T1F-E1-AY?

The UPD166007T1F-E1-AY supports 30 A DC continuous load current at T_C = 25°C. Derating applies per thermal resistance: with R_th(ch-a) = 55°C/W on standard PCB, maximum ambient temperature drops to ~85°C at full 30 A. The device self-limits short-circuit current and shuts down thermally above 150°C channel temperature.

How does the UPD166007T1F-E1-AY implement short-circuit protection?

The UPD166007T1F-E1-AY uses dual-condition short-circuit detection: (a) load current exceeding programmable I_L(SC) thresholds (e.g., 50 A at V_CC−V_IN = 12 V), or (b) output voltage drop V_ON > 0.65–1.45 V after 0.8–3.5 ms turn-on delay. Upon detection, it latches OFF and asserts fault current (3.5–12 mA) on the IS pin until reset via IN pin toggle.

Can UPD166007T1F-E1-AY be used in reverse-battery scenarios?

Yes - the UPD166007T1F-E1-AY includes reverse-battery protection with V_DS(rev) = 0.6–0.84 V across −40 to +150°C. Power dissipation under reverse polarity is limited by the intrinsic body diode and internal resistors; external load impedance must restrict reverse current. No external components are required for basic protection.

What is the function of the IS pin on UPD166007T1F-E1-AY?

The IS pin on UPD166007T1F-E1-AY delivers proportional load current sensing (I_IS = I_L/K_ILIS, K = 8300–11000) for real-time monitoring and fault diagnosis. During normal operation, it outputs scaled current; under thermal or short-circuit fault, it sources fixed 3.5–12 mA. If unused, IS must be connected to GND via ≤20 kΩ resistor.

Does UPD166007T1F-E1-AY require an external gate driver or bootstrap capacitor?

No - UPD166007T1F-E1-AY integrates a charge pump that generates sufficient gate voltage for full MOSFET enhancement from 8 V V_CC, eliminating need for external gate drivers, bootstrap capacitors, or high-side level shifters. This simplifies PCB layout and reduces BOM count in space-constrained automotive modules.
