Description

The VN5E010AH is a single-channel high-side

driver manufactured in the ST proprietary

VIPower M0-5 technology and housed in the tiny

HPAK package. The VN5E010AH is designed to

drive 12 V automotive grounded loads delivering

protection, diagnostics and easy 3 V and 5 V

CMOS compatible interface with any

microcontroller.

The device integrates advanced protective

functions such as load current limitation, inrush

and overload active management by power

limitation, overtemperature shut-off with auto-

restart and overvoltage active clamp. A dedicated

analog current sense pin is associated with every

output channel in order to provide ehnanced

diagnostic functions including fast detection of

overload and short-circuit to ground through

power limitation indication, overtemperature

indication, short-circuit to Vcc diagnosis and

ON- and OFF-state open-load detection.

The current sensing and diagnostic feedback of

the whole device can be disabled by pulling the

CS_DIS pin high to allow sharing of the external

sense resistor with other similar devices

VN5E010AH 3.3 Application information Current sense and diagnostic The current sense pin performs a double function (see Figure 33: Current sense and diagnostic): ? Current mirror of the load current in normal operation, delivering a current proportional to the load one according to a know ratio KX. The current ISENSE can be easily converted to a voltage VSENSE by means of an external resistor RSENSE.

Application information 3.3.1 VN5E010AH Short to VCC and OFF-state open-load detection Short to VCC A short-circuit between VCC and output is indicated by the relevant current sense pin set to VSENSEH during the device OFF-state. Small or no current is delivered by the current sense during the ON-state depending on the nature of the short-circuit.
