STMicroelectronics VN808SR13TR

Overview

VN808SR13TR from STMicroelectronics is an octal high-side power switch IC fabricated in VIPower M0-3 technology, designed for driving grounded loads in industrial control systems. It delivers 0.7 A per channel with 150 mΩ R_DS(on), operates up to 45 V supply, and integrates junction/case thermal shutdown, current limitation, short-circuit protection, and undervoltage lockout. Used in PLC output modules and motor interface circuits where load independence and fault resilience are critical.

For engineers reviewing the VN808SR13TR datasheet, VN808SR13TR pinout, VN808SR13TR application, or VN808SR13TR equivalent, key selection criteria include per-channel thermal autonomy, V_CC/2-compatible logic inputs, open-source status reporting, reverse ground loss detection, and IEC 61000-4-4 ESD immunity up to 4 kV.

Technical Context

The VN808SR13TR implements eight independent high-side switches sharing a common V_CC and GND, each with dedicated input and dual-pin output (e.g., Output 1 = pins 35–36). Each channel features active current limiting (0.7–1.7 A), junction thermal shutdown at 150–200 °C with 7–15 °C hysteresis, and case thermal shutdown at 125–135 °C.

Protection logic includes automatic restart after junction overtemperature (restarting at T_R = 135 °C), permanent shutdown until case cools to T_CR = 110 °C upon case overtemperature, and immediate disable on ground pin disconnection. Status pin (pin 20) provides open-drain diagnostic signaling for thermal faults.

FAQ

What is the maximum continuous output current per channel?

The VN808SR13TR supports 0.7 A DC continuous output current per channel at T_J ≤ 125 °C and V_CC = 24 V, as specified in Table 3 of the datasheet. Current is internally limited to 0.7–1.7 A under short-circuit conditions, with thermal foldback preventing damage during sustained overload.

How does the STATUS pin indicate fault conditions?

The STATUS pin is an open-source output that remains low during normal operation and floats high (requiring external pull-up) only during thermal fault events-specifically when junction temperature exceeds TTSD or case temperature reaches TCSD. It does not assert for undervoltage or ground-loss events, which cause silent channel disable.

Can VN808SR13TR drive inductive loads without external flyback diodes?

No. Although the device includes internal clamp voltage specification (V_demag = V_CC−47 to V_CC−57 V), ST's datasheet explicitly requires external freewheeling diodes across inductive loads to ensure safe energy dissipation and prevent voltage overshoot beyond absolute maximum ratings.

Is VN808SR13TR compliant with RoHS and REACH regulations?

Yes. The VN808SR13TR is packaged in PowerSO-36 ECOPACK®-compliant format, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed in Section 7 of the official ST datasheet (Doc ID 11624 Rev 5).
