Product details
Overview
IRS53365DC from Infineon Technologies is a high-side smart power switch IC with integrated current sense, overtemperature protection, and diagnostic feedback. It delivers 5 A continuous output current, operates from 4.5 V to 28 V supply, and features <1.5 Ω on-resistance at 25 °C. It is used in automotive body control modules for load driving such as headlights, fans, and solenoids.
For engineers reviewing the IRS53365DC datasheet, IRS53365DC pinout, IRS53365DC application, or IRS53365DC equivalent, key selection criteria include its programmable current limit threshold (typically 7.5 A), fast short-circuit response time (<2 µs), diagnostic flag accuracy (±10% current sense), and AEC-Q100 Grade 1 qualification for automotive use.
Technical Context
The IRS53365DC integrates a vertical power MOSFET with analog current sensing, thermal shutdown, and open-load detection. Its internal charge pump enables full enhancement of the high-side switch across the entire 4.5–28 V supply range without external bootstrap components.
Diagnostic functionality includes a dedicated INH/FLT pin that asserts low during overcurrent, overtemperature, or open-load faults. The device supports PWM switching up to 25 kHz and maintains ±10% current sense accuracy over temperature and supply voltage variation.

Pinout & Package
IRS53365DC is housed in a thermally enhanced PG-TO263-7 package (D²PAK-7) with exposed drain pad for efficient heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS | Power supply input | Connects to battery rail; supports 4.5–28 V operation with reverse polarity protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side smart switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN32F0A | Integrated 3-phase gate driver + ARM Cortex-M0; no built-in current sense amplifier | Targeted at BLDC motor control, not single-load switching | Choose only if multi-phase motor control is required alongside high-side switching |
| BTS724G | Lower RDS(on) (0.9 mΩ), higher current rating (60 A peak), but no analog current sense output | Designed for high-power loads (e.g., starter relays); lacks diagnostic granularity for low-current sensing | Select when peak current >10 A is needed and analog IS feedback is unnecessary |
Compared with STSPIN32F0A and BTS724G, the IRS53365DC uniquely balances medium-current capability (5 A), integrated analog current sense (0.5 V/A), and automotive-grade diagnostics-making it optimal for distributed body electronics where load visibility and functional safety are critical.

FAQ
What is the maximum allowable junction temperature for IRS53365DC?
The absolute maximum junction temperature is 175 °C. Thermal shutdown activates at 175 °C with 25 °C hysteresis, allowing safe recovery before re-enabling. Derating curves in the datasheet specify continuous current vs. ambient temperature and PCB copper area.
Does IRS53365DC require an external bootstrap capacitor?
No. IRS53365DC uses an internal charge pump to generate gate voltage above VS, eliminating the need for an external bootstrap capacitor. This simplifies layout and improves reliability in space-constrained automotive modules.
Can IRS53365DC drive inductive loads directly?
Yes. It includes integrated clamp diode emulation and fast demagnetization control. When driving relays or solenoids, the device manages flyback energy without external freewheeling diodes, provided layout minimizes parasitic inductance in the OUT path.
How is the current sense output (IS pin) calibrated?
The IS pin provides factory-trimmed 0.5 V/A scaling with ±10% tolerance over temperature and supply voltage. No external calibration is required; MCU ADC reads the voltage directly to derive load current, supporting diagnostic logging and adaptive control algorithms.
