STMicroelectronics VND9016AJTR

Overview

VND9016AJTR from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-16 package, designed for 12 V grounded loads with CMOS-compatible 3 V/5 V control inputs. It delivers 16 mΩ typical on-state resistance per channel, 50.6 A current limitation, and <0.5 µA standby current, enabling deep cold-cranking operation per LV124 Rev 2013 in ADAS radar and sensor supply applications.

For engineers reviewing the VND9016AJTR datasheet, VND9016AJTR pinout, VND9016AJTR application, or VND9016AJTR equivalent, key selection criteria include multiplexed analog current sense accuracy (±7% at 3.7 A), configurable latch-off vs. auto-restart fault response, and reverse-battery protection via self-turn-on behavior - all validated under AEC-Q100 Grade 0 (-40 °C to +150 °C).

Technical Context

The device integrates two independent VIPower M0-9 high-side switches with dedicated input, sense enable (SEn), and channel select (SEL) logic. Each channel features programmable fault handling via FaultRST pin, supporting either latched shutdown or auto-restart modes based on external pull configuration.

Its diagnostic architecture uses a single CS pin to multiplex proportional current feedback (K = 8250 ±7% at IOUT = 3.7 A), open-load detection (2–4 V threshold), short-to-VCC identification, and thermal/overload flags - all synchronized through SEn and SEL timing windows with ≤20 µs inter-channel transition delay.

FAQ

What is the maximum continuous output current per channel?

The VND9016AJTR supports up to 3.7 A continuous output current per channel at 25 °C with 13 V supply, limited by thermal design. Its 50.6 A current limitation (ILIMH) is a short-circuit protection threshold, not a continuous rating. Derating applies above 25 °C per the R_thj-board = 7 °C/W thermal resistance and ambient temperature conditions specified in Table 4.

How does the multiplexed CS pin distinguish between channel diagnostics?

The CS pin outputs diagnostic signals based on SEn and SEL states: when SEn = high, SEL = low selects OUTPUT0 for current sense or open-load detection; SEL = high selects OUTPUT1. During overload or thermal shutdown, CS drives VSENSEH (5–7.5 V) regardless of SEL state. OFF-state open-load detection requires VINx = 0 V and VOUTx > 2 V, verified within 250 µs after input transition.

Can VND9016AJTR operate with a 3.3 V microcontroller interface?

Yes - all logic inputs (INPUT0/1, SEn, SEL, FaultRST) are fully compatible with 3 V CMOS outputs, with VIH = 2.1 V min., VIL = 0.9 V max., and 0.2 V hysteresis. Input clamp voltages (6–8.5 V) protect against overshoot, and leakage currents remain below 10 µA across -40 °C to +150 °C, ensuring robust interfacing with 3.3 V MCUs without level-shifting.

What happens during reverse battery connection?

Under reverse battery (VCC = -13 V), the integrated VIPower structure conducts with RDSON = 16 mΩ and VF = 0.7 V at -3.7 A (150 °C), limiting reverse current to 13 A. GND must be externally protected with a diode/resistor network per datasheet guidance. The device remains functional post-event if reverse energy stays below EMAX = 19 mJ, verified per JEDEC JESD22-A114F testing.
