Pin settings
L6585DE
6/33
Pin n.
Name
Function
13
PFG
PFC gate driver output. The totem pole output stage is able to drive power
MOSFETs with a peak current of 300 mA source and 600 mA sink (typ. values).
14
HBCS
3-level half-bridge current monitor for current control.
The current flowing through the HB MOSFET is sensed through a resistor. The
resulting voltage is applied to this pin.
First level threshold (1.05 V, active during run mode): in case of threshold
crossing the IC reacts with frequency increase in order to limit the half-bridge
(and lamp) current.
Second level threshold (1.6 V, active during ignition and run mode):
- Ignition: in case of threshold crossing during the frequency shift, the IC reacts
with frequency increase in order to limit the lamp voltage and preventing
operation below resonance.
- Run mode: in case of threshold crossing because of current spikes (due, for
example, to capacitive mode / cross-conduction) longer than 200 ns the
L6585DE is latched in low consumption mode to avoid damage to the
MOSFETs.
Third level threshold (2.75 V, active during ignition and run mode):
- Ignition: in case of threshold crossing during frequency shift (e.g. caused by
choke saturation), the IC latches to avoid damage to the MOSFETs.
- Run mode: in case of threshold crossing by a hard switching event (spike
duration equal to around 40 ns) an internal counter is increased. After around
350 (typ.) subsequent hard switching events the IC is latched in low consumption
mode.
15
GND
Ground.
16
LSD
Low side driver output: the output stage can deliver 290 mA source and 480 mA
sink (typ. values).
17
VCC
Supply voltage of both the signal part of the IC and the gate driver.
Clamped with a Zener inside.
18
OUT
High-side driver floating reference. This pin must be connected close to the
source of the high side power MOSFET.
19
HSD
High-side driver output: the output stage can deliver 290 mA source and 480 mA
sink (typ. values).
20
BOOT
Bootstrapped supply voltage. Bootstrap capacitor must be connected between
this pin and OUT pin.
Patented, integrated circuitry replaces the external bootstrap diode by means of
a high voltage DMOS, synchronously driven with the low side power MOSFET.
