Product details
Overview
TDE1898CFP from STMicroelectronics is a 0.5A industrial high-side intelligent power switch in Multipower BCD technology, designed for driving inductive or resistive loads in harsh environments. It features internal clamping diode (VCL = 45–55 V), differential inputs with ±7–15 V common-mode range and hysteresis, open-load detection (1–6 mA), and dual diagnostic outputs. Used in PLC output modules for solenoid control.
For engineers reviewing the TDE1898CFP datasheet, TDE1898CFP pinout, TDE1898CFP application, or TDE1898CFP equivalent, key selection criteria include supply voltage range (18–35 V), thermal shutdown threshold (135 °C), output status driver capability (2–4 mA), and SIP9 package thermal resistance (70 °C/W).
Technical Context
The TDE1898CFP integrates an NDMOS high-side switch with internal clamp diode, current limiting, and thermal protection in a monolithic Multipower BCD process. Its differential input stage supports wide common-mode operation (–7 to +15 V) and includes 50–400 mV hysteresis to reject noise during industrial switching transients.
Two dedicated diagnostic outputs (D1/D2) provide fault signaling per ISO/IEC 61000-4-4 compliance: D1 indicates open load or overtemperature; D2 is omitted in TDE1898C (vs. TDE1897C), simplifying diagnostics for single-fault reporting in deterministic control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 0.5 A nominal; internally limited to 0.75–1.5 A short-circuit current for robust overload handling |
| Supply Voltage Range | 18–35 V; supports industrial 24 V ±25 % bus with undervoltage lockout at 11 V (falling) / 15.5 V (rising) |
| Clamp Voltage (VCL) | 45–55 V across VS–VO; enables fast demagnetization of inductive loads without external snubbers |
| Input Threshold Hysteresis | 50–400 mV; prevents chatter on noisy control lines in factory-floor environments |
| Thermal Shutdown | 135 °C junction limit with 30 °C hysteresis; ensures self-protection during sustained overload or poor heatsinking |
| Open Load Detection | 1–6 mA threshold; detects disconnected solenoids or broken wiring before actuation attempts |
| Diagnostic Outputs | D1 only (TDE1898C); logic-level signals for CPU polling without external level-shifting circuitry |
Pinout & Package
The TDE1898CFP uses the SIP9 (Single In-line Package, 9-pin) housing with 2.54 mm pitch, optimized for vertical PCB mounting and low thermal resistance (Rth j-amb = 70 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Power Ground Reference | Common return path for internal logic, diagnostics, and output current sensing |
| 2 (OUT) | High-Side Output Terminal | Switched 0.5 A load connection; internally clamped to VS − 45 V during demagnetization |
| 3 (VS) | Positive Supply Input | 18–35 V main rail; powers DMOS gate driver and internal bias circuits |
| 4 (OS) | Output Status Driver | Sinks 2–4 mA to drive external LED indicator; voltage drop ≤5 V at IOS = 2 mA |
| 5 (D1) | Diagnostic Output 1 | Active-low fault signal: L = open load, overtemperature, or undervoltage |
| 6 (D2) | Diagnostic Output 2 | Not connected (NC) in TDE1898C; distinguishes it from TDE1897C which uses D2 for short-to-VS detection |
| 7 (+IN) | Differential Input Positive | Accepts control signal referenced to –IN; common-mode range extends to VS − 7 V |
| 8 (–IN) | Differential Input Negative | Reference node for differential input stage; enables noise-immune digital command reception |
| 9 (NC) | No Connect | Unused pin; must remain unconnected per datasheet layout guidance |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Clamp Diode | Eliminates need for external flyback diode in solenoid/relay drivers, reducing BOM count and PCB area |
| Differential Input Stage | Rejects >15 V common-mode noise on factory floor wiring, enabling direct interface with 24 V PLC backplane signals |
| Open Load Detection | Verifies load continuity before activation-prevents false "on" state assumptions in safety-critical valve control |
| Thermal Protection with Hysteresis | Shuts down at 135 °C and re-enables only after cooling to 105 °C, preventing cycling during transient overloads |
| Output Status LED Driver | On-chip 2–4 mA constant-current source drives panel-mounted LEDs without external current-limiting resistors |
Applications
| PLC Digital Output Module | Industrial Solenoid Driver |

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 |
|---|---|---|---|
| VNS1NV04PTR | 0.4 A rating, SO-8 package, no integrated clamp diode, single diagnostic output | Lacks open-load detection and internal clamping; requires external flyback diode and sense resistor | Preferred for space-constrained designs where thermal load is low and external components acceptable |
| IPS1032HTR | 3.2 A rating, HTSSOP-20 package, 45 V clamp, dual diagnostics, higher quiescent current (12 mA) | Higher current capacity and enhanced diagnostics but larger footprint and greater standby power | Selected when driving larger solenoids or requiring redundant fault reporting in SIL2-compliant systems |
Compared with VNS1NV04PTR and IPS1032HTR, the TDE1898CFP delivers optimal balance of integrated protection (clamping, open-load, thermal), compact SIP9 form factor, and low-system-cost implementation for 0.5 A industrial loads.

FAQ
What is the function of Pin 6 (D2) on the TDE1898CFP?
Pin 6 (D2) is a no-connect (NC) terminal in the TDE1898CFP. Unlike the TDE1897C, which uses D2 to signal short-to-VS faults, the TDE1898C implements single-diagnostic reporting via D1 only-reducing system complexity where only one fault type needs immediate CPU attention.
Can the TDE1898CFP drive a 24 V, 1.2 W solenoid directly?
Yes: a 1.2 W solenoid draws 50 mA at 24 V, well within the 0.5 A rated output. The device's 250–425 mV output drop at 625 mA ensures minimal power loss, and its internal clamp diode safely handles the solenoid's inductive kickback without external components.
How does the differential input improve noise immunity?
The ±IN inputs accept signals with up to 15 V common-mode offset relative to VS, rejecting ground-bounce and EMI-induced voltage spikes on long cable runs. Combined with 50–400 mV hysteresis, this prevents false triggering in electrically noisy factory environments.
Is the SIP9 package RoHS-compliant and lead-free?
Yes-the TDE1898CFP SIP9 package conforms to RoHS Directive 2011/65/EU and is lead-free, with matte tin lead finish. STMicroelectronics documentation confirms full compliance for industrial-grade versions released post-2006, including this part's manufacturing baseline.
