Product details
Overview
TDE1707CFP from STMicroelectronics is an intelligent high- and low-side power switch IC delivering 0.5 A output current, operating from 6 V to 48 V supply, with integrated +5 V regulator, LED status driver, thermal shutdown, and GND/VS open-wire protection - used in industrial PC I/O and numerical control machine load switching.
For engineers reviewing the TDE1707CFP datasheet, TDE1707CFP pinout, TDE1707CFP application, or TDE1707CFP equivalent, key selection criteria include configurable high-/low-side topology, adjustable turn-on delay via external capacitor, internal voltage clamping up to 70 V, and robust fault handling for inductive loads in factory automation systems.
Technical Context
The TDE1707CFP integrates dual-output topology (pin 2 = high-side, pin 8 = low-side) with independent current-sensing comparators and a dedicated delay circuit triggered at 4 V on pin 3. Its internal 5 V regulator (±5% accuracy, 6 mA max output) powers external proximity sensors or logic, while the LED driver sinks or sources 3 mA depending on output state.
Fault management includes real-time overload detection via output saturation monitoring, short-circuit current limiting (0.7–1.5 A), and thermal shutdown activation at junction temperatures exceeding 150 °C. The 25 μs minimum delay on fault clearance ensures stable recovery before re-enabling the IN signal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 500 mA at VS ≤ 32 V; derates to 300 mA at 32–48 V - defines maximum resistive/inductive load drive capability |
| Supply voltage range | 6 V to 48 V - supports wide industrial DC bus operation including 24 V and 36 V systems |
| Saturation voltage | 1.1–1.6 V at 500 mA - determines conduction loss and thermal dissipation in high-side mode |
| Internal clamp voltage | 55–70 V - protects against inductive kickback without external TVS diodes |
| Regulated AUX voltage | 4.5–5.5 V at ≤5 mA - powers external proximity detectors or level-shifting circuitry |
| Turn-off time | 15 μs typical - enables fast response in safety-critical or cyclic control applications |
| Delay capacitor trigger | 4 V threshold on pin 3 - sets precise timing for programmable turn-on delay (0.65–2 ms with 1 nF–1 µF) |
Pinout & Package
Package: SO-8 (ECOPACK® compliant), 150 °C/W junction-to-ambient thermal resistance, surface-mount footprint per Figure 8 in DS13872 Rev 1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LED driver | Sinks or sources 2–4 mA to indicate output ON/OFF state - polarity depends on high-/low-side configuration |
| 2 | High-side output | Switches load between VS and this pin - used when load connects to GND |
| 3 | Delay capacitor source | Provides 2–6 µA charge current to external capacitor - sets programmable turn-on delay duration |
| 4 | GND | Power and signal reference ground - also used for open-wire detection |
| 5 | Input | CMOS-compatible control input with 2–3 V threshold and 300 mV hysteresis - immune to noise in industrial environments |
| 6 | Regulator voltage source | Outputs regulated +5 V (±5%) - powers external sensors or logic; short-circuit protected to 30–50 mA |
| 7 | Supply voltage (VS) | Primary power input (6–48 V); reverse-polarity protected up to −48 V |
| 8 | Low-side output | Switches load between this pin and GND - used when load connects to VS |
Key Features
| Feature | Design Value |
|---|---|
| Configurable topology | Single device supports both high-side (load-to-GND) and low-side (load-to-VS) switching - reduces BOM count in multi-configuration systems |
| Programmable turn-on delay | 25 μs minimum base delay, scalable to 2 ms using external capacitor on pin 3 - prevents false triggering during power-up transients |
| Integrated status reporting | LED driver provides real-time output state feedback without external components - simplifies diagnostics in PLC I/O modules |
| Comprehensive fault protection | Simultaneous detection of overcurrent, overtemperature, supply reversal, GND/VS open-wire, and output short-circuit - eliminates need for discrete protection circuits |
| Inductive load rated | Rated for 150 mJ energy dissipation - supports solenoids, valves, and contactors common in NC machines without snubber networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar intelligent power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VND5E025AK | Single-channel, 2.5 A rated, no integrated LED driver or adjustable delay | Higher current, but lacks status feedback and programmable timing - requires external components for diagnostics | Choose when >500 mA load current is required and system-level status indication is handled separately |
| IPS1025H | 2.5 A, built-in current sense analog output, no +5 V regulator or LED driver | Supports real-time current monitoring but cannot power external sensors - needs separate 5 V supply | Prefer when closed-loop current feedback is critical and auxiliary power is available elsewhere in design |
Compared with VND5E025AK and IPS1025H, the TDE1707CFP uniquely combines 500 mA switching, integrated +5 V regulation, LED status reporting, and programmable delay - making it optimal for space-constrained, self-contained I/O modules where component count and diagnostic capability are prioritized over raw current rating.

FAQ
What is the difference between TDE1707BFP and TDE1707CFP?
The TDE1707BFP and TDE1707CFP share identical electrical specifications and functionality. The only distinction is packaging: BFP uses tape-and-reel packaging (order code TDE1707BFPT), while CFP uses tube packaging (order code TDE1707CFP). Both use the same SO-8 ECOPACK® package with identical thermal resistance values (Rth(JA) = 130 °C/W).
Can TDE1707CFP drive inductive loads without external flyback protection?
Yes - the device includes internal voltage clamping up to 70 V (typ.) and is rated for 150 mJ inductive energy dissipation. This allows direct driving of solenoids, relays, and small DC motors without external flyback diodes in most 24 V industrial applications, provided layout minimizes parasitic inductance.
How is the LED driver polarity determined in high-side vs. low-side configurations?
In high-side mode (load connected to GND), the LED driver sinks current when the output is ON; in low-side mode (load connected to VS), it sources current when ON. This automatic polarity selection is handled internally based on voltage comparison between pins 2/8 and VS/GND - no external configuration is needed.
What is the minimum external capacitor value needed to achieve the maximum 2 ms delayed turn-on time?
A 1 µF capacitor on pin 3 achieves the maximum 2 ms delayed turn-on time (typ.), as specified in Table 5. The relationship is linear: 1 nF yields ~0.65 ms, 10 nF yields ~6.5 ms (beyond spec limit), so 1 µF is the practical upper limit for guaranteed 2 ms compliance per DS13872 Rev 1.
