VB029012Y overview
VB029012Y is a component documented by STMicroelectronics. The PDF description identifies it as "HIGH VOLTAGE IGNITION COIL DRIVER POWER I.C. Jul-1999." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

- Note 2: time from input switching VNEG until collector voltage equal to 200V. (*) Vd -Vbe(on) (**) This thermal flag shift cannot be activated for lower than 125°C .
- During V IN high (≥4V) the VB029, VB029SP, VB029(011Y) VB029(012Y) increase current in the coil to the desired, internally set current level.
- When the collector current exceeds 4.5A, the diagnostic signal is turned high and it remains so, until the load current reaches 5.8A (second threshold).
- During the coil current switch-off, the primary voltage HVC is clamped by a series of Zener diodes at an internally set value Vcl, typically 360V.
- A maximum overshoot of 20V is allowed.
Topics covered by the datasheet
The document includes sections related to:
- DESCRIPTION
Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
