STMicroelectronics IPS160H

Overview

IPS160H from STMicroelectronics is a 60 V, 2.5 A rated monolithic high-side switch in PowerSSO12 package, designed for industrial I/O control of resistive, capacitive, and inductive loads with ground-referenced configuration. It features 60 mΩ R_DS(on), non-dissipative cut-off protection, fast active demagnetization, and integrated diagnostics including open-load-in-off-state, thermal shutdown, and overload reporting via open-drain DIAG pin. Used in PLC output stages driving solenoids and valves.

For engineers reviewing the IPS160H datasheet, IPS160H pinout, IPS160H application, or IPS160H equivalent, key selection considerations include its programmable cut-off delay (via external capacitor on CoD), ground/VCC disconnection protection, undervoltage lock-out thresholds (6.9 V on / 6.5 V off), and SIL-capable diagnostic architecture compliant with IEC 61131-2.

Technical Context

The IPS160H implements a high-side power switch with integrated logic interface, active V_DS clamp for fast inductive load demagnetization (V_demag = V_CC − 68.5 V typical), and current-limiting circuitry triggering at 3.8 A (typ) before entering cut-off mode. Its DIAG pin delivers latched fault reporting for thermal shutdown (T_JSD = 150–190 °C), cut-off, and open-load conditions - all independent of IN pin state.

Cut-off delay time (t_coff) is programmable from 500 μs to 5 μs via external capacitor (10–100 nF) on CoD pin; disabling cut-off requires a 1 kΩ resistor to GND. The device maintains functional operation during V_CC or GND disconnection events until undervoltage thresholds are crossed, enabling robust field wiring tolerance.

Key Specifications

FAQ

What is the maximum continuous output current supported by IPS160H?

The IPS160H guarantees a minimum output current limitation of 2.5 A under all operating conditions (−40 °C to 125 °C, 8–60 V). Its typical R_DS(on) of 60 mΩ results in ≤375 mW conduction loss at 2.5 A, enabling reliable operation with appropriate PCB copper area and thermal vias. Peak transient current capability exceeds 4.2 A per datasheet Table 8.

How does the CoD pin function, and what happens if left floating?

The CoD pin must never be left floating: it programs cut-off delay time via external capacitor (10–100 nF) or disables cut-off entirely when tied to GND with a 1 kΩ resistor. If left unconnected, internal leakage may cause unpredictable cut-off timing or failure to enter cut-off mode, risking thermal damage during sustained overload. Datasheet Figure 2 and Section 2.4 mandate explicit termination.

Can IPS160H drive inductive loads without an external flyback diode?

Yes - the IPS160H integrates active V_DS clamp (fast demagnetization) that pulls OUT to V_CC − 68.5 V (typ) during turn-off, dissipating inductive energy internally. This eliminates need for external flyback diodes in most applications. However, for single-pulse demagnetization energy exceeding 3000 mJ (e.g., large solenoids at 24 V), an external Schottky diode is required per Figure 13 and Section 7.

What diagnostic faults are reported on the DIAG pin, and how are they distinguished?

The DIAG pin reports three latched faults via open-drain low-state: thermal shutdown (T_J ≥ 150 °C), cut-off activation (current limit exceeded for t_coff), and open-load-in-off-state (V_OUT > 4 V with IN = LOW). All share same pin polarity but differ in timing behavior: thermal and cut-off faults reset automatically after cooling or restart delay (t_res), while open-load fault resets only upon load reconnection.
