INTELLIGENT POWER DEVICE
Oct. 30, 2015
1. Overview
1.1 Description
Family:
PD166031AT1U is part of 2nd Generation Intelligent Power Devices (IPD). They are N-channel high-side switches
with charge pump, voltage controlled input, diagnostic feedback with proportional load current sense and embedded
protection function. Family includes up to 14 devices depending on on-state resistance, package and channel number
combination.
Scalability:
Variety of on-state resistance combined with standardized package on pin-out give user high flexibility for unit design
depending on target load.
Robustness:
Because of advanced protection method, 2nd Generation Intelligent Power Devices achieve high robustness against
long term and repetitive short circuit condition.
1.2 Features

3.6 Feature Description
3.6.1 Driving Circuit
The high-side output is turned on, if the input pin is over VIH. The high-side output is turned off, if the input pin is open
or the input pin is below VIL. Threshold is designed between VIH min and VIL max with hysteresis. IN terminal is
pulled down with constant current source.

The dynamic clamp circuit works only when the inductive load is switched off. When the inductive load is switched off,
the voltage of OUT falls below 0V. The gate voltage of SW1 is then nearly equal to GND. Next, the voltage at the
source of SW1 (= gate of output MOS) falls below the GND voltage.
SW1 is turned on, and the clamp diode is connected to the gate of the output MOS, activating the dynamic clamp circuit.
When the over-voltage is applied to VCC, the gate voltage and source voltage of SW1 are both nearly equal to GND.
SW1 is not turned on, the clamp diode is not connected to the gate of the output MOS, and the dynamic clamp circuit is
not activated.

3.6.2 Device behavior at over voltage condition
In case of supply voltage greater than Vload dump, logic part is clamped by ZDAZ (35V min). And current through of
logic part is limited by external ground resistor. In addition, the power transistor switches off in order to protect the load
from over voltage. Permanent supply voltage than Vload dump must not be applied to VCC.

3.6.3 Device behavior at low voltage condition
If the voltage supply (VCC) goes down under VCC(Uv), the device outputs shuts down. If voltage supply (VCC) increase
over VCC(Cpr), the device outputs turns back on automatically. The device keeps off state after under voltage shutdown.
The IS output is cleared during off-state.

3.6.4 Loss of Ground protection
In case of complete loss of the device ground connection, but connected load ground, the device securely changes to off
if VIN was initially greater than VIH state or keeps off state if VIN was initially lower than VIL state.
In case of device loss of ground, IN and SEN terminal will/ could/ might be at VCC voltage.

3.6.5 Short circuit protection
Turn-on in an over load condition including short circuit condition
The device shuts down automatically when condition (a) is detected. The sense pin output Iis,fault. Shutdown is latched
until the next reset via input pin. The device shuts down automatically when condition (b) is detected. The device
restarts automatically in power limitation mode. The device shuts down automatically when condition (c) is detected
and restarts automatically in absolute thermal toggling mode. The device starts current limitation when (d) is detected.
The sense pin output Iis,fault during power limitation mode or thermal toggling mode.
(a) IL > IL(SC)
(b) deltaTch > dTth
(c) Tch > aTth
(d) Von > Von(CL1) after td(CL)
Over load condition including short circuit condition during on-state
The device runs automatically into power limitation mode when condition (a) is detected once after Von < Von(CL2).
The device shuts down automatically when condition (b) is detected. The device restarts automatically in power
limitation mode. The device shuts down automatically when condition (c) is detected and restarts automatically in
absolute thermal toggling mode. The sense pin output Iis,fault during power limitation mode or thermal toggling mode.
(a) Von > Von(CL2)
(b) deltaTch > dTth
(c) Tch > aTth
Power limitation control
Current limitation control with IL(CL) when auto restart from deltaTch protection.
During the current limitation operation and Von>Von(CL1), the sense pin outputs Iis,fault. Even auto restart from delta
Tch protection, if Von<Von(CL2) depends on short circuit impedance condition, the device does not operate as current
limitation with IL(CL). In this case, the sense pin output sense current at on-state, Iis,fault at off-state during toggling
operation with power limitation mode.
Absolute thermal toggling
Current limitation control with IL(TT) when auto restart from absolute Tch protection.
During the current limitation operation and Von>Von(CL1), the sense pin outputs Iis,fault. Even auto restart from
absolute Tch protection, if Von<Von(CL2) depends on short circuit impedance condition, the device does not operate as
current limitation with IL(TT). In this case, the sense pin output sense current at on-state, Iis,fault at off-state during
toggling operation with thermal toggling mode.

The device has a function which controls Ron in order to improve KILIS accuracy at small load current conduction.
Von (VCC-OUT) is proportionate to IL under normal conditions. Under IL<IL(NL) condition, Ron is controlled to
increase to be Von=Von(NL)=30mV(typ).

Current sense output
The device output analog feedback current proportional to output current from IS pin. In the case of much higher
current than nominal load current, current sense output is saturated. In the case of much lower current than nominal load
current, current sense output is above 5A if output current is above IL(CSE) max, current sense output is below 2A,
IIS,offset max, if output current is below IL(CSE) min.

Sense current under fault condition
The device output IIS,fault, constant current, from IS pin under fault condition such as after over current detection,

attenuated depends on VCC-VIS voltage. Operation point as IIS,fault output is also depends on RIS condition. For
example, In the case of RIS=1k, IIS,fault could be 3.5mA to 9mA, VCC-VIS could be 4.5V to 10V, VIS could be 9V
to 3.5V if VCC=13.5V. In the case of RIS is higher than 1k, Operation point as IIS,fault is lower than specified value
but VIS should be higher than RIS=1k condition.

3.6.9 Driving Capability
Driving Capability is specified as load impedance. Over current detection characteristics is designed above Driving
Capability characteristics. If estimated load impedance which comes from peak inrush current is lower than Driving
Capability characteristics, this means, the device does not detect inrush current as over current and does not shutdown
the output. Depend on the conditions, Power Limitation function may work during inrush current. If estimated load
impedance which comes from peak inrush current is lower than Driving Capability characteristics, Power limitation
disappear within 30ms. This parameter does not mean that the device can drive the resistive load up to Driving
Capability characteristics.
